Dry Lining Back Boxes

Dry lining back boxes, also known as plasterboard back boxes, are designed for installing sockets and switches into hollow walls like plasterboard and stud partitions. Unlike surface or solid-wall back boxes, they are fixed directly into the plasterboard itself, allowing wiring accessories to sit flush with the wall for a neat finish.

These back boxes use built-in fixing lugs or clamps to grip the plasterboard securely from behind, removing the need for wall chasing. This makes them suited for homes, office partitions, and renovation projects where cables run within wall cavities.

At Rexel and Denmans, our range of dry lining back boxes are available in single (1 gang) and double (2 gang) sizes to suit different socket and switch layouts.
