After completing the work of covering the walls with plasterboard, the last stage remains - installing sockets in the plasterboard. The work is simple and does not require great knowledge and skills in electrical engineering - it can be done on your own, without inviting a specialist, even for an untrained person. But the installation of sockets must be carried out carefully and efficiently, since the level of resistance depends on this. fire safety housing.

Installation Tools

In order to install sockets without interruption while searching for the missing tool, you need to prepare it in advance. You will need the following:

• tape measure and marker for marking holes;
• a drill and a special cutter (crown) for drilling a hole in drywall. The diameter of the working part of the cutter should be equal to the diameter of the standard socket cup - 6.8 cm. If you don’t have a drill, you can use a screwdriver for this task;
• air bubble level (short enough to 0.3 m);
• a screwdriver with an indicator for the presence of voltage in the wires being tested;
• a screwdriver (Phillips or standard depending on the shape of the slots on the bolts) necessary when attaching the socket box, wires and the socket itself;
• a stationery knife necessary for stripping insulation from wires when connecting them to terminals.
• Preparatory activities

The locations of the sockets are determined before the start of wall covering work.

You also need to lay the wires before you start covering the walls in order to hide them under the drywall.

Installation is carried out in the following sequence:

• First, a frame is assembled for attaching drywall sheets and attached to the wall. Its ends are attached to the floor and ceiling of the room.
• If a partition is being built, one side is sheathed at once. Wiring will be laid along it.
• A wiring diagram is created and the locations of the socket boxes are marked on it.
• In the vertical parts of the frame, holes are drilled with a drill for wiring.
• Wires laid to the locations of the socket boxes should be placed in a corrugated plastic sheath and routed through the holes prepared in the frame.

The cost of the protective shell is low, and possible damage and high humidity It protects perfectly, so there is no reason to save on its purchase.

• The most optimal would be a cable with 3 cores in double insulation (with a core diameter of 1.5 to 2.5 mm). If you plan to use electrical appliances with high current consumption, the cross-section of the wires must be increased.
• Wires laid under the casing should be securely secured with pieces of wire or plastic clamps.

Once you have finished laying the wires and marking their exit points on the plan, you can begin attaching the gypsum board to the frame.

Selecting installation locations

Socket installation locations modern rules is not regulated, so the installation of the socket can be done where it is convenient to use it.

According to the standards established in Europe, the socket must be located at a height of 0.3 m from the floor. In some cases, this is justified, but, for example, in the kitchen, such an arrangement will force the housewife to make a lot of bows when turning on and off kitchen electrical appliances while cooking.

It is also better to install the outlet behind the aquarium higher for ease of connecting the backlight, filter, and compressor. And the electrical cords will not lie on the floor and interfere with movement around the room.

How to install

Installation of a socket in drywall begins with preparing holes for installing socket boxes. Plastic socket boxes will be inserted into the holes, and sockets will already be fixed into them.

When creating a hole, you need to do the following:

• First, you need to find the installation location in accordance with the diagram. Then the specified distance from the floor is measured with a tape measure and a mark is placed;
• Using a level, find the center of the future hole horizontally and place a cross;
• when drilling holes for socket boxes, use an electric drill with an attachment in the form of a cutter (crown);
• Aligning the center of the cutter with the center of the cross, carefully cut out a hole.

If it is necessary to install a row of sockets, you need to mark the holes before drilling the first one, which will allow you to get an even row of sockets without distortions.

Installation of a socket box

The socket box is made in the form of a plastic cup, which must be installed and secured in the finished hole in the drywall.

The socket for drywall has four screws. Two are designed for attaching it to drywall and two are for attaching the metal trim to the outside.

Installation of the socket box is carried out in the following sequence:

• Before installing the socket box in place, you must pass the wires through the hole in its bottom. If several points are installed, you need to supply power to them using a daisy chain connection. With this connection, wire sections are passed from the first socket box to the second, from the second to the third, etc.
• Despite the simplicity of daisy chain connection, there is a danger excessive heat contacts of the first socket due to the fact that the total load of all other points passes through them. Therefore, experienced electricians prefer to make connections through sizes - plastic caps with an internal conical thread designed to insulate twists.
• Using sizy phase wire twists with several wires according to the number of connected sockets. The same twist can be done on neutral wire, but since it is not so susceptible to heating, it can be run as a train.

Since the wires may burn or break during operation, it is necessary to leave a margin of at least 10 cm in length.

• Using a level, the socket box is set horizontally and secured with clamps on the drywall. In this case, you need to make sure that it does not pinch the wires.

Sometimes it happens that the distance from the wall to the drywall is less than the height of a standard rosette cup. Then in the wall material, using a hammer drill or concrete chisel, you need to make a recess of the appropriate depth. You can prepare the recess before covering it, but then you will have to determine its location with pinpoint accuracy.

Connecting wires

Before you begin connecting the wires, you must turn off the power to switchboard. You can make sure there is no voltage using.

If there is no voltage, you can start connecting the wires:

1. All decorative elements are removed from the socket;
2. The bolts on the socket terminals are loosened, the wires are inserted and the bolts are tightened until they stop. When using a three-wire wire, the ground wire is connected to the middle terminal;
3. The socket with the connected wires is inserted into the socket box and secured in it using spacers or fastening bolts on the socket box;
4. Before finally fixing the socket, you should once again check the tightness of the wires on the terminals;
5. All that remains is to put on the frame and install the cover. When tightening the screw, you do not need to make any great efforts so as not to crush the plastic parts.
6. When installing several adjacent sockets, you can purchase a common frame for them, from 2 or more.

Video instructions

Perhaps, when installing the first socket, some difficulties may arise due to not knowing how to install the socket, but installing the next ones will be much easier. The main thing is to follow the recommendations and exercise maximum care when conducting electrical installation work. The above technology will not only allow you to install a socket in drywall - it is also applicable when installing switches and double sockets.

Before installing the socket on the drywall, you need to carry out a series of preparatory work. Moreover, some of the work is done during the installation of the partition.

Preparatory work

Sockets are installed according to the socket arrangement plan. According to the same plan and single-line design diagram, electrical wiring around the room is carried out. Electrical wiring is carried out inside the partition structure or under the sheathing of a plasterboard wall. Wiring in progress electric cable with copper conductors and double (VVG cable) or triple insulation (NUM cable). According to the technology, the cable must be enclosed in electrical installation corrugation or special plastic pipes, for electrical installation work.

The places where it is planned to install surface-mounted sockets must be reinforced inside the structure, transversely wooden blocks. The bars will serve as a support on which the sockets will be attached.

Tool for installing sockets on drywall

For work you will need the following tool:

• Construction level and pencil for marking;
• A drill with an attachment called a crown. The crown is designed for drilling large holes;
• Assembly knife and screwdriver with a small slot.

Important! Any work with electrical wiring must be carried out with the power supply turned off. Before work, check that the power supply is disconnected in the circuit where you plan to work.

Marking the space for the socket

The marking is made according to the socket placement plan. It is worth paying attention to the installation height of the sockets. She should be a wound all over the room. For a single level of installation of sockets, you can take the bottom of the installation box (socket box) or its middle.

About the socket box for plasterboard walls

A socket box for plasterboard is a special mounting box with a design for durable fastening. The essence of the fastening design is as follows. Special plastic spacers are made in the socket box, which from the inside cling to the sheets of drywall when the mounting screws rotate.

Drilling a hole for a socket box

It is worth noting that the socket boxes can be fastened together to install 2-5 sockets in a row. The hole or holes for the socket boxes are drilled in the drywall using a drill with a crown-type attachment. The diameter of the crown is selected according to the size of the socket box.

Before drilling, markings are made and the center of installation of the socket box is looked for. Drilling is done at medium speed.

The photo shows drilling drywall for two socket boxes. By the way, To install built-in switches on drywall, the same mounting boxes are used.

Installing a socket on drywall is easy

Let's go through the steps of installing a socket on drywall.

• Drill holes for the socket box;
• Route pre-routed cables into drilled holes;
• Break out perforated holes in the socket boxes for cables;
• Install socket boxes in pre-drilled holes and route electrical cables into them;
• If you install two or more sockets, you need to place jumpers between the sockets;
• The end of the cable protruding from the box should not exceed 12 cm in length. Strip the insulation from the cable by 10 cm. Strip the ends of the cable cores by 5 mm;
• Connect the cable to the outlet terminals. Maintain the same wire color for all outlets in the room. We must connect the yellow wire to ground. Phase and zero core we connect, for example, like this: the blue wire to the right terminal of the socket, the brown wire to the left terminal of the socket;
• Tighten the terminal screws securely and tighten them again;
• Unscrew the mounting screws in the socket boxes that are located along its edges;
• After connecting the wires, straighten them and insert the socket into the socket box. Insert the sockets so that the mounting screws fit into the holes on the socket frame. Turn the sockets horizontally and tighten the mounting screws;
• For additional fastening, tighten the screws of the spacer “mustache” of the socket. They will move apart and attach to the walls of the socket box;
• The installation of the socket is completed by installing a protective cover and decorative frame.

IN modern construction interior decoration and leveling walls are very often performed using plasterboard sheets. In addition, internal partitions can be quickly created from this material. Thanks to many positive qualities, drywall has become widespread for repair and construction work. The installation technology consists of several stages. This includes electrical installation work, including installation of sockets in drywall, as well as switches and other electrical installation products. This operation is not particularly difficult and can be done with your own hands without outside help.

Preparatory work

How to make a socket in drywall? The design of plasterboard walls allows the installation of almost any type of sockets, both single and with two or more sections. However in the classic way installation will fail. For these purposes you will need a special one. It must be fireproof, since plasterboard sheets are flammable materials. With the help of a socket box, the installation of sockets and switches in drywall is greatly facilitated.

The point where electric current comes out through the socket and is considered the most dangerous element of the entire structure. Therefore, for the manufacture of such socket boxes, self-extinguishing plastic is used. If the outlet gets hot during operation, the heat generated will not transfer to the drywall. This ensures fire protection.

It is necessary to select a socket box taking into account the location of the plasterboard sheets relative to the wall. For the most effective solution The task of how to install a socket in drywall will require an individual choice, especially if the selected sheets are mounted close to the wall. Each socket box has pressing tabs that can be moved apart using screws. When purchasing, it is advisable to check their performance. The configuration and dimensions of socket boxes differ from standard models, used for ordinary walls.

There are differences between installation boxes for different purposes. Typical socket boxes are mounted inside the wall in a pre-drilled recess and then fixed with mortar. Models intended for installation in drywall are installed in the hole, after which they are pressed against inside sheathing with fastening tabs moving along the screw thread. After this, the socket in the drywall is securely fastened.

How to make a hole in drywall for an outlet

Before drilling a hole into which the drywall socket box will be mounted, it is necessary to accurately determine and mark the location of its future location. There are standards used by specialists during installation. For example, it is 30 cm, and from the floor to the switch - 90 cm. These dimensions may vary depending on specific operating conditions. Ease of use must also be taken into account, especially in kitchens and bathrooms where household appliances and equipment. It is also necessary to take into account the wiring diagram laid in each room.

The location finally selected for installation is marked with a pencil or construction marker using a building level. After this, you can cut a hole in the drywall for the outlet. The very first hole is drilled in the center of the mark, after which the cutter is used. If you don't have a power tool, you can use construction knife. The socket box is first applied to the wall and outlined along the contour. Flaw this method is jagged edges and the formation of large chips.

Therefore, the most ideal option When you need to make holes in drywall for sockets, an electric drill with a special bit with a diameter of 68 mm is considered. Exactly the same cutters are used when installing spotlights in drywall. The procedure is very simple. First, the attachment is installed on the drill. Next, a hole is drilled using a pilot drill. After this, the main hole is cut using a crown. Strong pressure is not required, since a high-quality crown can easily cut any drywall.

Installation of socket boxes and sockets

After the hole is drilled in the marked location, you can begin installing the socket box. Previously sharp knife a chamfer is cut around the entire circumference. This procedure is prerequisite high-quality installation, since the socket box has an outer edge up to 1.5 mm thick.

If there is no chamfer, the edges of the side will protrude beyond the surface level. This difference will have to be compensated with a large amount of putty, which may result in an unsightly mound. If a chamfer is cut, the side easily fits into it and becomes flush with the plane of the wall.

Next is the direct installation of the socket box, which will be needed to attach the socket to the drywall. The plastic plugs located along the contour should be broken off and the ends of the connected wires inserted into the holes. After this, the product is inserted into the hole and tightened with adjusting screws. They are quite long, so it is recommended to use a screwdriver instead of a screwdriver. The screws are tightened until the fastening tabs are pressed against the inside of the plasterboard sheet.

The next step is to install the socket in the drywall yourself. To do this, unscrew the two remaining screws on the socket box. The decorative cover is removed from the socket, after which the previously routed wires are connected to it. The entire structure, along with the wires, is installed in the socket box and secured with unscrewed screws.

The decorative trim is put on after completion finishing walls Installation technology single socket quite suitable for installing a whole block. You will need the same set of tools required quantity socket boxes and sockets themselves.

How to install a socket block in drywall

First you need to measure the height at which the socket block is supposed to be installed and make the necessary marks. They act as beacons for drawing a horizontal line using a level. After this, the centers of future holes are marked, as well as their locations among themselves. Care is required here, since shifting one mark will shift the centers of other circles. After marking, you can attach the socket to the drywall.

A crown is inserted into an electric drill required diameter, after which holes are drilled according to the marks. All socket boxes are assembled into a common block, the plugs are broken out of them, and the wires are brought out into the resulting holes. The assembled block is inserted with a certain force; on each glass you need to bend the latches at the top and bottom so that the structure can stand on seat. Then all installed socket boxes are fixed in the wall using adjusting screws. Direct installation into drywall is carried out after finishing finishing works.

There are no strict restrictions on the number of sockets. However, experts recommend installing more than four sockets in one row. In addition, installation of sockets in drywall must be carried out according to certain rules. For example, the distance between the centers of the holes should be 71 mm. First, the first point is measured, and after it all the others. Before securing the outlet to the drywall, you should remove the thin barriers between the holes. This is done using a hacksaw, after which the block easily falls into place.

In this article we will look at how to install socket box for plasterboard. I hasten to assure you that in fact, there is nothing complicated here and everyone can perform this action independently. Especially if you have detailed information at hand step by step instructions By

installation with photographs and comments from a professional. The material presented in this article describes in detail the entire installation process from beginning to end. Using it as intended socket box for plasterboard will be installed quickly, efficiently, without any problems or difficulties.

As a rule, all the socket boxes we are interested in, regardless of color and manufacturer, have the same principle of fixation in drywall. For this purpose, special tabs are provided on its back or side, and they play the main role in installation. But first things first, let’s look at the installation sequentially.

Preparing the socket box for installation

Let's start by explaining the basic elements. Socket boxes for drywall, unlike, have four screws on their front part, not two. U different manufacturers they can be located differently, but in all versions they perform the same functions.

Two screws are external; they protrude from the socket box and perform the function of fixing the frame of the socket or switch mechanism.

An example is shown in the figure below.
This option for mounting a switch or socket can only be used if it has an iron or plastic frame.

As you can see in the following figure, the other two screws are slightly recessed into the plastic; they can be located next to the frame mounting screws on the left and right, as in our example, or located above and below.

When impacting these screws Phillips screwdriver The socket box fixing tabs will be set in motion by means of a screw drive.

We turn the screw, the foot moves. In our example, the legs are metal, but on some socket boxes they can be plastic; this does not affect the quality of fixation in any way.

On the back of the socket box there are special holes, blanks for the wire. Cut out any you like. It is best if the wire enters the socket box from the back, this will greatly facilitate the further installation of the socket or switch mechanism.

Cut a hole.

The socket box is ready for installation.

How to install a socket box for drywall?

For this we need a tape measure. With its help, we measure all the necessary distances and dimensions of the future location of the outlet or switch. Place a cross at the installation location.

There are some installation standards that you can use if you wish:

• the installation height of the socket is 30 centimeters from the floor to the center of the socket;
• installation height of the socket in the bathroom above washing machine- 1 meter;
• installation height of the socket above the tabletop kitchen set- 1 meter 20 centimeters;
• switch installation height - 90 centimeters from the floor to the center of the switch and 18 centimeters from; the edges of the doorway of the future door, excluding the frame and trim.

These sizes are not essential; if you wish, you can take any that are convenient for you.

Now, we need to make a hole in the drywall for the socket box. The diameter of the socket box is usually standard size 68 millimeters.

You can make a hole in various ways, I will give examples of the most common ones in amateur electricians:

• completely cut through the outline of the socket box with a knife;
• Drill the outlined outline of the socket box with a drill, and then cut through it with a knife.

The disadvantage of all the above methods is the uneven edges of the resulting hole, which can greatly complicate the installation process. In addition, if we talk about installation specifically in drywall, it is worth noting that this material is very fragile and brittle. That is why, to make a hole, it is best to use a wood crown with a diameter of 67 millimeters specially designed for this purpose. This crown is also used for making holes for spotlights. In the picture below you can see what it looks like.

Rice. Crown for socket boxes and spotlights.

The crown for sockets is installed on a drill or screwdriver. Then, setting the power tool in motion with a crown, a hole is cut in the wall.

The hole is ready. We insert the wire into it.

If the drywall has already been installed, and the wire comes out of it into a small hole and sticks out of the wall, which very often happens when hired builders work, installation is also possible. To do this, bend the wire upward and, very carefully, right under it, so as not to damage the insulation, slowly drill a hole for the socket box. The decorative overlay frame of the rosette will cover approximately 1 centimeter from the edge of the hole. Or, as an alternative, you can push the wire into the wall and then carefully drill. Here, the main thing is to make sure that the crown does not fly inside and cut the wire.

We install a socket box for drywall

We insert the wire into the hole in the socket box, which we cut in advance.

And we install the socket box, having previously positioned the mounting screws to fix the socket frame in a horizontal position.

We tighten the screws of the claw drive until the socket box is slightly retracted into the hole, this will mean that the claws have reached the limit, then we loosen it a little and check the reliability of its fixation.

This is what it looks like with reverse side drywall, in our case chipboard.

Installation of the socket box in the drywall is complete. Next, you can go to or , You can see how to do this in the relevant manuals.

As you can see from the instructions above, installing drywall socket boxes is a fairly simple and easy process, plus you get some financial savings and experience.

Also, if you wish, you can familiarize yourself with.

By installing a socket box for drywall yourself, we save:

• call an electrician - 200 rubles
• installation of a socket box in plasterboard - 200 rubles

Total: you get - 400 rubles, plus the invaluable experience gained in independent installation.

The plasterboard bit, 68 mm in diameter, is narrow-profile and is used for drilling holes intended only for installing socket boxes.

Cutter for working with 6.8 cm socket box (solid)

The socket consists of two parts: a visible decorative part and a socket box - a terminal block hidden from view, which serves as a connection point various wires to ensure safe electrification. It is round and is produced in certain standard sizes in diameter and height, the compliance of which is verified by GOST standards and norms.

There are three types of socket boxes:

1. for concrete, they are a plastic cup without fixing elements, installation is carried out in cement mortar;
2. for wood - made of metal;
3. for plasterboard, the body material is plastic, special vertical pressure plates, plastic or metal, are placed on the side walls; by means of these fixing elements, the socket box is attached to the back side of the gypsum board sheet.

The usual diameter of manufactured socket boxes is 68-70 mm, which requires the use of special drills for installation. As for the decorative part of the rosettes, it is also divided into subtypes:

• with a closing curtain to protect children from electric shock;
• with protection from moisture and other aggressive environments– suitable for installation in extreme rooms (kitchen, bathroom);
• equipped with a grounding contact.

Characteristics of crowns

A special drill (mill) is used for sockets cylindrical with a cutting edge in the form of pointed teeth placed at a certain angle at the end. In the center of the device there is a drill around which the crown is placed. First, a drill penetrates into the material being processed, fixes the nozzle in a given position and performs alignment to cutting edge. This shape is optimal for efficient drilling and durability of the crown.

To install socket boxes, a crown is used, the diameter of which is 68 or 70, although the size range can vary from 33 to 150 mm. The length of the tool for installation work on installing an electrical terminal block is 60-65, although nozzles with a depth of 30 to 80 mm are available.

Crowns are divided into types:

• solid - consist of one thin-walled metal glass with teeth;
• collapsible - are a design made of a universal disk on which several glasses are placed various diameters in the shape of an unfinished cylinder.

Bimetallic cutters are also produced, which, in addition to processing fragile materials, are suitable for drilling metal and steel with sheet thicknesses of 1 mm or more. Popular manufacturers that produce 68 mm crowns include the brands Bocsh, HSS, Sigma, MTX, etc.

The Karat series cutter (Bosch) is used complete with an adapter and a centering drill, which allows you to process plasterboard walls, marble and wood. The HSS bit (Makitta) chambered for 13 mm is suitable for processing surfaces made of gypsum plasterboard, plastic, plywood and chipboard. Allows you to make holes in the wall with a depth of 3.2 cm. Equipped with a countersink.

Installation methods and types of tools for its implementation

There are three ways to install socket boxes:

1. linked to a profile;
2. without connection to the frame;
3. installation of a socket block.

Before choosing the installation method, prepare the tools, in addition to the crowns and socket boxes, use a drill, a screwdriver and the outer part of the socket.

Additionally you will need:

• building level;
• ruler or tape measure (to control the distance between block socket boxes);
• pencil for marking;
• a construction vacuum cleaner, which is used when making holes with a drill in drywall, so that less dust collects and does not clog the lungs.

For precise marking use laser level, which will allow work to be carried out with minimal deviations in calculations.

Type of marking made using a level

Profile-linked installation

This type of installation is the simplest. It applies if there is metal frame, and on sheets of drywall, you can confidently determine where the profiles are located based on the marks left by the heads of the screws. There is no risk of snagging wiring or getting into the middle of the profile when making holes, which guarantees safe installation.

Stages of work:

• markings are carried out for the location of sockets ( building level a horizontal and vertical line is drawn, the intersection of which indicates the location of the center of the future outlet);
• a cutter with a diameter of 68 mm is put on the drill;
• a hole is made;
• take a socket box, break out the plug on the side walls for laying the power cable;
• a wire is threaded into the holes from the former plugs;
• the socket box is inserted into the plasterboard wall and secured to it with clamping feet using a screwdriver;
• wiring is connected in the terminal mounting block;
• During finishing work, the electricity is turned off and the hole is covered with masking tape;
• Upon completion of all work, the outer part of the socket is put on.

If the sheets of drywall are already plastered and it is impossible to visually determine where the metal profiles or conductive cable are located, they resort to using a regular magnet, which they lean against the surface of the gypsum board and make the necessary notes. You can also cut holes on the gypsum board sheet even before the stage of covering the frame.

Installation of a block socket

Block sockets are called sockets that consist of several terminal blocks for simultaneous connection to a 220 V network, the Internet, TV, etc.

Installation nuances:

• the distance between the centers of block sockets should be 72 mm;
• calculations are transferred to the wall using a level;
• The cups of the socket boxes are connected to each other by cable C3A3 or “butterflies”, which are taken with a margin of 2 cm and assembled into a block;
• under level control, circles are cut out of the plasterboard wall, to which the block is applied and the correct calculation of the recesses is checked;
• the resulting holes are connected to each other with a chisel;
• the block is inserted and fixed to the wall with clamping bolts;
• Cables are routed between the socket boxes.

Connecting a block socket

Additional Installation Requirements

To ensure that the installation of socket boxes is carried out in accordance with fire safety regulations, is distinguished by quality and accuracy, adhere to following rules and recommendations:

• installation of electrical wiring must be completed before the start of the stage of covering the frame with gypsum board sheets; for these purposes, it is preferable to use a non-flammable flat cable of the VVGng LS type, which is placed in a corrugated sleeve with a self-extinguishing probe and secured with staples to the side shelves of the profile, the wiring should go to the location of the socket box;
• To prevent the material from cracking, when working with a crown, it is not recommended to press hard on the surface of the drywall sheet;
• installation of the socket box should be carried out 30 cm from the floor, before finishing work with gypsum boards begins;
• the dimensions of the recess between the original wall and the drywall must be 45 mm or more, otherwise the socket box will not fit through the hole made and will have to be further deepened;
• if there is gypsum board between the frame and the wall wooden floors or to increase the level of electrical safety, it is recommended to treat the edges of the installed socket box with gypsum plaster.

Sealing a rosette with gypsum plaster

You can find out how to install a socket using a bimetallic crown, the diameter of which is 68 mm, in compliance with installation standards, using the example video below.

Installation without reference to a profile

Sometimes it happens that the calculations are made incorrectly and after drilling in the hole for future sockets, a profile is visible, due to which it is impossible to push the block through and securely fix it in the recess. In this case, the crown is replaced with a regular knife on metal or with a chisel and make holes manually, removing 5-10 cm of the visible profile.

Incorrect installation, in which the profile prevents the placement of the socket box in the prepared hole.

The frame of the structure will not suffer from this, but the sheet of drywall itself may be deformed, and due to the inconvenient viewing angle there is a risk of injury. When cutting the profile, it is recommended to wear special installation gloves - they will protect your hands from unwanted cuts.
