Description

The Knightsbridge CL73PC is a BT master telephone socket with a polished chrome rounded edge faceplate constructed from 304 stainless steel. The socket provides the primary connection point for incoming telephone lines and includes a built-in surge arrestor and R/C circuit filter to protect connected equipment from voltage spikes on the line.

Designed for residential and light commercial installations requiring main line access, the master socket allows for line testing and fixed resistance checks without needing to disconnect the wiring. The screw terminals provide secure connections for incoming and outgoing telephone cables, and the socket conforms to BS 5733 standards for telephone outlet installations.

The 85.75mm square faceplate features rounded edges and a built-in gasket that sits flush against the wall, reducing dust ingress behind the plate. The polished chrome finish on the stainless steel provides a reflective surface that pairs with traditional and contemporary interiors where metallic accents are used across switches, sockets and door furniture. The 25mm minimum back box depth requirement matches standard UK electrical back boxes.

Frequently Asked

What is a master telephone socket?

A master socket is the primary connection point where the incoming telephone line from the external network enters the property. It includes filtering and surge protection components and allows line testing without disconnecting internal wiring. Secondary sockets elsewhere in the property connect back to the master socket.

What back box depth is required?

A 25mm minimum back box depth is needed for installation. The faceplate adds 7.5mm projection from the wall once fitted.

Is this a screw-fixed or screwless faceplate?

This is a screw-fixed faceplate. The two visible screw fixings at top and bottom secure the plate to the back box. For screwless variants in the same finish, search for Knightsbridge screwless telephone sockets.

What other finishes are available?

Knightsbridge produces this rounded edge master socket style in a range of finishes including brushed chrome, polished brass, satin brass, black nickel and white. Use the search function or filters to find other variants in stock at Niori.
