The British back-box family

Single / double gang

Knockouts where you need them

Knockouts around the box open only the cable or conduit entries the installation needs, keeping the rest of the box closed and tidy.

Knockout entries

One contact for boxes and conduit

Supplied alongside the conduit and cable tray, so the boxes come from the same supplier as the run that feeds them.

Qué es el CTM-BX-UK y para quién es

British standard back boxes are the pressed steel boxes that sit flush in a wall behind a switch, socket or accessory on UK-pattern installations. They are the metal knockout boxes an electrician screws the faceplate onto, sized so that BS-standard accessories fit and the wiring has room behind the plate. The pattern and dimensions are described by BS 4662.

We supply the boxes in the common single- and double-gang sizes and the 25, 35 and 47 mm depths that suit different wall build-ups, in pre-galvanized pressed steel with knockouts for cable and conduit entry. Sizes, depths, finish and any product-specific certification are confirmed with you per order and per destination market, and we supply them alongside the conduit and cable tray they connect to.
