Description

The Knightsbridge FP7300PB is a BT-type master telephone socket finished in polished brass with a flat plate design. The master socket provides the primary connection point for landline telephone service and includes a built-in surge arrestor and R/C filter, which allows service providers to perform line resistance checks remotely without needing to access the property.

Designed for residential and commercial installation, the socket fits a standard 25mm minimum back box depth and uses screw terminals for wiring. The flat plate profile projects just 2.5mm from the wall once fitted, giving a low-profile finish that suits both traditional and contemporary interiors. A built-in gasket behind the plate provides a flush seal against the wall, preventing gaps around the faceplate edge.

The 201 stainless steel plate is finished in polished brass, providing a warm metallic tone that pairs well with heritage, classical and warm-toned contemporary interiors. The polished finish develops a natural patina over time if left unsealed. The socket is certified to BS 5733 for UK telecommunications installation and carries an IP20 rating for indoor use.

Frequently Asked

What back box depth is required?

A 25mm minimum back box depth is needed for safe installation. The flat plate design projects just 2.5mm from the wall once fitted.

What's the difference between a master socket and a secondary socket?

The master socket is the primary connection point where your telephone line enters the property. It includes a built-in surge arrestor and R/C filter for line testing. Secondary sockets are extensions from the master and do not include these components.

Is this suitable for broadband?

Yes. BT-type master sockets carry both voice and ADSL broadband signals. Most broadband routers connect via an RJ11 plug into the lower filter port of a master socket or via a microfilter plugged into this outlet.

What other finishes are available?

Knightsbridge produces this flat plate telephone socket in a range of finishes including polished chrome, brushed chrome, polished brass, antique brass, matt black and white. Use the search function or filters to find other variants in stock at Niori.
