Description

The Knightsbridge CU4DIM is a 4-gang dimmer plate supplied unpopulated with four matching dimmer caps and screw cap covers. The plate is moulded from white thermoset resin with a gently contoured 7mm profile and rounded edges, designed to accept Knightsbridge dimmer modules or compatible third-party dimmer modules for a modular installation approach.

Designed for residential and hospitality settings where multiple dimmer controls are needed on a single faceplate, the unpopulated format allows electricians to specify and fit the exact dimmer modules required for the lighting circuits in question. The plate measures 146mm wide by 86mm tall, fitting standard UK double-gang back boxes when populated. The rounded edge profile softens the wall junction and the white finish integrates cleanly with standard white wall colours.

The thermoset resin construction includes built-in anti-microbial properties tested to ISO 22196:2011, reducing bacterial surface growth in high-touch environments such as care homes, hospitals, hotels and family bathrooms. The IP20 rating suits dry interior locations. The 25-year warranty covers manufacturing defects in the plate itself, though dimmer module performance depends on the modules chosen.

Frequently Asked

What dimmer modules does this plate accept?

The plate accepts Knightsbridge dimmer modules and most compatible third-party modular dimmers designed for UK standard back boxes. The plate arrives unpopulated, so the dimmer modules must be purchased separately and fitted by a qualified electrician.

What is the anti-microbial treatment?

The thermoset resin is moulded with an anti-microbial additive tested to ISO 22196:2011, which inhibits bacterial surface growth. This makes the plate suitable for care homes, hospitals, hotel rooms and family bathrooms where hand-contact surfaces benefit from reduced microbial presence.

What back box is required?

A standard UK double-gang back box (minimum 25mm depth recommended) is needed when the plate is populated with dimmer modules. The 146mm width matches the double-gang footprint.

Are the screw caps included?

Yes. The pack includes matching white screw cap covers to conceal the faceplate fixing screws once the plate is installed.
