Dry Lining Boxes – Circular

The circular dry lining box is one of those products you don’t think about until you need one — and then you really need one. Used primarily in stud partition and plasterboard walls, these white back boxes give you a clean, recessed mounting point for round-profile electrical accessories like shaver sockets, round media outlets, and certain doorbell or intercom fitments. Available in 35mm and 45mm depths, so you can match the box to the accessory and the wall construction without compromise.

Dry lining boxes differ from standard pattresses because they’re designed specifically for plasterboard installation. The fixing lugs or wings expand behind the board as you tighten them, gripping the plasterboard from behind without needing a solid noggin or timber backing. That makes them quick to fit during first or second fix, and genuinely useful when you’re chasing through a finished wall and can’t easily get to the stud frame.

Where Circular Dry Lining Boxes Fit Into the Job

Electricians and first-fixers use these across domestic and light commercial work. New build stud wall construction, office partition fit-outs, bathroom shaver point installations, and any situation where a round accessory needs a proper flush-fitted back box rather than sitting on the surface. The 35mm depth suits shallower applications and most standard accessories, while the 45mm gives you extra room where wiring bulk or cable management is a factor.

The white finish blends with standard plasterboard and plaster surrounds without standing out before accessories are fitted. Nothing fancy, but that’s the point — a circular dry lining box should disappear behind the faceplate and get on with doing its job. These are priced at trade rates, which makes stocking a mix of depths a sensible call when you’re running a van and never quite know what depth the job will call for.
