Dual (1G+2G) Dry Lining Box (White)

The dual 1G+2G dry lining box is one of those fittings that earns its place on any first fix electrical job. It combines a single-gang and a double-gang aperture in one back box, which means you can run a socket and a switch from the same location without needing two separate boxes or any creative plasterboard surgery. Available in 35mm and 45mm depths, it suits most standard stud partition and dry lining situations.

Dry lining boxes are designed specifically for plasterboard walls. Rather than being surface-mounted or set into blockwork, they grip the board from behind using lugs or wings that bite as you tighten the fixing screws. No plugs, no drilling into masonry, no mess. It is the standard approach for stud walls in residential and commercial fit-outs, and electricians who work these jobs regularly will know the routine well.

Where the Dual 1G+2G Dry Lining Box Earns Its Keep

The dual format is particularly useful in rooms where you need both a switched spur and a socket at the same point, or a USB charger outlet alongside a light switch. Kitchens, home offices, and commercial fit-out partitioning are all common applications. Rather than chasing in two separate boxes and patching around them, a single dual box keeps the plasterboard intact and the finish cleaner.

The 45mm depth variant gives a bit more room to work with when you have a busier back box, which is worth considering if conduit entries or thicker cables are involved. The 35mm version suits tighter stud spacings or shallower voids where depth is limited.

White finish means it sits neatly behind white faceplates without any shadow or colour mismatch around the edge. A small detail, but one that matters on a clean install. These are available in bulk from DTS, which makes them straightforward to stock ahead of larger fit-out contracts.
