Buster and Punch 1G Dry Lining Back Box

The Buster and Punch 1G Dry Lining Back Box is a single-gang plastic enclosure from Buster and Punch designed for recessed mounting of switches and sockets into plasterboard and hollow walls. It combines a discreet, square-flanged form with built-in fire-stopping features for safe, compliant installations.

Form and function meet in a white ABS chassis with a square outer flange and a recessed internal cavity sized for standard accessories. Two blue side-mounting lugs on opposite sides secure the unit to the reverse of dry lining walls and the interior includes multiple circular and rectangular knock-outs for cable entry.

Built for durability, the box features brass threaded screw inserts for secure faceplate fixing and grey intumescent gaskets pre-fitted along the top and bottom interior edges. Internal embossed markings include BS5733, the CE mark and part numbers, and a label identifies the unit as part of an ENVIROGRAF dry lining & gasket set.

Engineered to preserve the fire integrity of a wall, the pre-fitted intumescent gaskets expand in heat to provide up to 1 hour of protection as part of a compliant installation. The recessed cavity and knock-outs make wiring straightforward during new installs or renovations.

Installation is simple: tighten the blue side lugs with screws to clamp the box firmly to the reverse side of a plasterboard wall and secure a faceplate to the internal brass inserts. The product carries the CE mark and comes with a 2 year warranty for added peace of mind.
