The PCDMBBTS2B is a double secondary telephone socket from the BG Evolve range, finished in matt black and built using the BG Euro Modular system. The BG Evolve range is new on the outside with its polycarbonate front plates and contrasting frame, but has the same internal technology as the BG Nexus Metal range. With interchangeable front plates, the Evolve range allows you to move with the trends without losing the level of quality and reliability.
