British General Nexus Metal Master Telephone Socket Polished Chrome (304FT)

Hi JohnDavey, This telephone socket has an 86 x 86mm faceplate (95 x 95 is somewhat oversized for current standards unfortunately).

Hi, thank you for your product enquiry. Telephone lines do not carry very much power at all, so they do not experience the same restrictions as mains power connections do. Thus there is no legal requirement for this British General Nexus Metal Master Telephone Socket Polished Chrome to be installed by a professional.
