The Appleby Dry Lining Boxes Dual 35 mm is a flush-mount dry lining back box made for plasterboard or cavity wall installations that can hold two separate 1-gang electrical accessories (essentially a dual box). It’s moulded from flame-retardant thermoplastic with tough, adjustable yellow nylon lugs that grip plasterboard (about 6.35–15 mm thick) so it won’t slip into the cavity during fitting. A large front flange helps align with faceplates, and it has two side cable knockouts plus a 25 mm base knockout for easy wiring entry, with an internal depth of 35 mm for wiring space.
