BSR Telephone Socket
The Powermax BSR Telephone Socket serves as a critical termination point for analog or digital voice lines in commercial infrastructures. This module employs a standard RJ11 port configuration to support standard telephony hardware. The black matte exterior meets modern architectural requirements for dark-themed hardware. It integrates seamlessly into professional office environments where aesthetics and functionality must align. Technicians utilize this specific outlet for structured cabling projects requiring reliable voice frequency handoffs.
The internal architecture features high-conductivity copper alloy contacts. These contacts receive a gold plating layer to mitigate the effects of atmospheric oxidation. Reliable signal transfer remains consistent across the service life of the installation. The socket housing consists of reinforced polycarbonate. This material provides excellent dielectric properties and thermal stability. It resists impact damage during the rough-in phase of construction. The mechanical design ensures the RJ11 jack remains seated firmly during cable tension.
Installation teams benefit from the standardized 86mm square footprint. This dimension ensures compatibility with standard BS-type mounting boxes. The unit provides sufficient internal clearance for cable bending radii within a 35mm back box. Rear-facing screw terminals allow for rapid conductor termination. These terminals utilize a pressure plate design to secure wires without shearing the copper. The BSR series maintains a low-profile aesthetic once mounted. It sits flush against the wall surface to minimize accidental impact. The included mounting screws feature matching black heads to maintain visual uniformity.
The mechanical design includes a spring-loaded shutter system. This mechanism blocks environmental debris from entering the port when no cable is connected. It prevents the accumulation of dust on the internal pins. Consequently, the electrical path remains clear for future connections. The black finish is molded directly into the polymer. This prevents surface scratching from revealing a different substrate color. The unit withstands the mechanical stresses of high-traffic office environments. Procurement managers select this component for large-scale rollouts due to its build quality and compliance with standard electrical accessory dimensions.

I’ve been looking for the Powermax BSR range to match my other black switches. This telephone socket is easy to wire up and the internal terminal feels durable. My only small issue is the screws provided were a bit short for my specific deep mounting box, but I used the old ones and it’s firm. Great value for money for a sleek finish.

The black finish is very neat and modern. We used these for our new office desks in Westlands and they look much better than the standard white ones. Connections are solid, no loose ports when plugging in the RJ11 cable.

Good quality RJ11 socket. It fits perfectly into the wall box and the matte black doesn’t show fingerprints easily.
