Richard Comlay from Dolphin Media and Design experienced supply issues from some US manufacturers with their accessory plates.
Our solution was an adapter plate that allowed US Decora styled products to be mounted into a UK 2-gang plate. Mounting from behind via 2 x M3 studs welded to the back of the plate, allowed the decora panel (in this case a HDBT transmitter) to fit seamlessly. The unit was then mounted into the preinstalled 2g back box on site. – Problem Solved!
