Telephone Extension Outlet - Brushed Chrome Flat Plate

The Knightsbridge FP7400BC is a BT-type telephone extension outlet with a brushed chrome flat plate faceplate and screw terminals. The socket is designed as a secondary outlet connected to a master telephone socket, allowing a landline handset to be used in a different room without running additional external cabling from the network entry point.

Designed for residential properties, home offices and commercial buildings where landline access is needed in multiple rooms, the outlet fits into a standard 25mm minimum back box depth. The flat plate design projects just 2.5mm from the wall surface once installed, giving a lower profile than traditional raised faceplates and sitting flush with painted or papered wall finishes.

The 201 stainless steel faceplate is finished in brushed chrome, which pairs comfortably with other brushed chrome electrical accessories, chrome door furniture and cooler-toned contemporary interiors. The built-in gasket behind the faceplate prevents plaster dust and paint from entering the back box during installation or redecorating. Screw terminals simplify the connection of standard telephone cable cores, and the earth terminal allows for proper grounding in metal back boxes.

Product Specification Sheet

What is the difference between a master socket and an extension socket?

The master socket is the primary connection point where the telephone line enters the property from the external network. Extension sockets like this one are secondary outlets wired from the master, allowing handsets to be used in additional rooms. Extension sockets cannot function without a master socket already installed.

What back box depth is required?

A 25mm minimum back box depth is needed. The recessed depth of the outlet itself is 19.8mm, and the faceplate projects just 2.5mm from the wall surface once fitted.

Is this compatible with broadband filters?

BT-type extension sockets like this are compatible with standard inline broadband filters when connecting a combined telephone and ADSL/VDSL setup. For fibre broadband delivered via a separate ONT, the telephone socket operates independently of the broadband connection.

What other finishes are available in the flat plate range?

Knightsbridge produces this style in multiple finishes including polished chrome, matt black, white, antique brass and brushed brass. Use the search function or filters to find other variants in stock at Niori.
