Wall Switch Plates Less Mechs
Let your imagination go a bit nuts, if you need a 6 gang data plate you can built one, 5 gang TV point… no problems you can build it. In fact you can combine TV points, data points or 1 way, 2 way, neon, intermediate, duo, engraved switches and dimmers.
It doesn’t matter if you want upgrade in the future because all the parts are available to upgrade from one gang set up to another or the same if you want to take something away. The system is completely modular and you don’t have to replace the entire unit just the part you want to change.
