Dry Lining Boxes – 2 Gang

The 2 gang dry lining box is the go-to back box for twin socket and switch installations in stud partition walls and plasterboard dry lining systems. Available in 35mm and 45mm depths, these white plastic boxes are designed to be fitted from the front face of the board without needing access from behind — which is usually a wall, or sometimes someone’s hopes and dreams of a tidy first fix. Fix directly into the plasterboard using the built-in lugs, and the job is done without any masonry cutting or chasing required.

First fix electricians and dry liners use these constantly. Whether you’re fitting twin sockets across a commercial fit-out or running back boxes through a stud wall in a domestic extension, the 2 gang dry lining box is the standard solution. The 35mm depth suits most modern double socket and twin switch configurations, while the 45mm option gives you the extra clearance needed where wiring is heavier or where the installation requires a bit more room to work.

2 Gang Dry Lining Box — Depth Options Explained

Choosing between 35mm and 45mm comes down to what’s going on behind the faceplate. The 35mm box works perfectly well for most standard twin socket positions, especially where cable management is straightforward. The 45mm box is the better choice when you’re dealing with larger conductors, multiple cables entering the same box, or simply when you want more room to terminate neatly. Neither depth is wrong — it just depends on your install.

Both versions accept standard UK 2 gang faceplates, so there’s no need to overthink compatibility. The plasterboard lugs grip the board face securely once tightened, holding the box flush and firm. No filler, no mess, no drama. These are available in bulk at pricing that makes sense for trade accounts running multiple installations at once — picking up a decent quantity at this price is just sensible site planning.
