Kenable Dry Lining Plasterboard Back Box - 2 Gang - 35mm

A dry lining back box, also known as a pattress box, is designed for installation into hollow walls, such as those made from plasterboard or partition panels. It provides a secure mounting point for electrical accessories like switches and sockets.

Double Gang (2G) refers to the size of the mounting box, indicating it is designed to accommodate two standard-sized electrical accessories side-by-side, such as a twin socket or a light switch and a socket.

The lugs are typically threaded and can be rotated with a screwdriver. Advancing the screw moves the lug outwards to grip the back of the plasterboard, while retracting it loosens the grip. Adjust them until they firmly hold the box against the wall.

This specific model is designed for dry lining (hollow) walls. For solid brick walls, you would typically use a surface-mount box or a different type of 'chasing' box that is designed to be sunk into masonry.

The flange is a lip around the edge of the box designed to cover the cut-out in the plasterboard. It helps to hide any imperfections in the cutting process and provides a neat finish against the wall surface.

RoHS (Restriction of Hazardous Substances) compliance means that the product contains restricted levels of certain hazardous materials, such as lead, mercury, and cadmium, making it safer for consumers and the environment.

This box uses standard fixing centres, which are the industry-standard distances between the screw holes used to attach faceplates to the back box.

Ensure the adjustable lugs are fully tightened against the inner surface of the partition board. Verify the board thickness is within the 6-20mm range supported by the lugs.

Check that the back box is fully inserted and the flange is making contact with the wall surface. Ensure the wall opening is not too large for the flange to cover effectively.

Ensure you are using the designated cable access points. If necessary, carefully enlarge the access point slightly with a suitable tool, ensuring not to compromise the box's integrity.

Confirm the wall opening dimensions match the back box size. If the opening is too large, the flange should cover it. If too small, carefully enlarge the opening.
