Kenable Dry Lining Plasterboard Back Box Pattress Box - 1 Gang 35mm

A dry lining back box, also known as a pattress box, is designed to be installed directly into plasterboard or stud walls. It provides a secure, flush mounting point for electrical accessories like switches and sockets.

This refers to the internal depth of the box from the front face (where the accessory mounts) to the back. It indicates the space available for wiring and the back of the accessory.

No, this specific Kenable back box is designed for dry lining applications (plasterboard/stud walls) and is not suitable for installation in solid masonry walls.

The box features integrated clips that grip the plasterboard from behind once inserted. Ensure the cutout is accurate and the plasterboard is of sufficient thickness for the clips to engage securely.

This is a single-gang box, so it is suitable for one standard UK electrical accessory, such as a single light switch, a single socket outlet, or a single data/communication faceplate.

Yes, the product description states it conforms to BS5733, which are relevant British Standards for electrical accessories and enclosures.

Check that the cutout was made accurately to the dimensions required. If the cutout is too large, consider using a larger pattress box or a suitable filler.

Verify the thickness of the plasterboard. The clips are designed for standard plasterboard thicknesses. Ensure the clips are fully extended and gripping the board from behind. If the plasterboard is too thin or brittle, the clips may not hold effectively.

Ensure the correct single-gang accessory is being used and that the back box is oriented correctly. The box is designed for standard UK single-gang accessory spacing.
