1 Gang Grid Faceplate Part M Compliant - Anthracite Curved Edge

The Knightsbridge 1-gang grid faceplate is an 86mm square anthracite thermoset resin faceplate designed to hold a single grid module from Knightsbridge's Curved Edge modular switch system. The faceplate carries Part M compliance through its light reflectance value of approximately 8.9, which meets Building Regulations requirements for contrast between the plate, module switch, and wall surface in accessible environments.

Built for public buildings, care homes, commercial offices and residential properties where accessibility standards apply, the faceplate accepts any single Curved Edge grid module — switches, sockets, dimmer modules, data ports. The thermoset resin construction resists impact better than standard thermoplastic faceplates and maintains its colour under UV exposure, making it suitable for high-traffic areas and locations near windows. The IP20 rating means it's designed for dry indoor use only.

The anthracite finish provides a dark neutral tone that reads nearly black in most lighting but shows a subtle warmth compared to pure matt black finishes. The thermoset material carries inherent anti-microbial properties verified to ISO 22196:2011, which reduce bacterial surface colonisation in clinical, catering and hygiene-critical environments. The faceplate projects 7mm from the wall once fitted and carries a 25-year warranty against material or manufacturing defects.

Product Specification Sheet

What is Part M compliance and why does it matter?

Part M of the UK Building Regulations sets accessibility requirements for new buildings and major refurbishments. This faceplate meets Part M through its light reflectance value (LRV) of approximately 8.9, which provides sufficient contrast against both the grid module switches and typical wall colours to aid visibility for users with impaired vision. It's required in public buildings, care facilities, and increasingly in new residential construction.

What grid modules fit this faceplate?

The faceplate accepts any single module from Knightsbridge's Curved Edge grid system — light switches, dimmer modules, 13A sockets, USB charging modules, RJ45 data ports, TV/satellite outlets. Grid modules are sold separately and clip into the faceplate aperture.

What's the difference between thermoset and thermoplastic faceplates?

Thermoset resin is harder and more impact-resistant than thermoplastic. It maintains its colour and surface finish under UV exposure and heat, whereas thermoplastic can yellow or warp over time. Thermoset also accepts anti-microbial additives more effectively, which is why it's specified in healthcare and catering environments.

Can this faceplate be used in bathrooms?

The IP20 rating means it's designed for dry indoor locations only. For bathroom zones requiring IP44 or higher protection, use Knightsbridge's dedicated IP-rated bathroom switches rather than the grid system.
