| You can cut a hole in the wall, put the c bar behind the wall, and attached the plate cover to the c bar. the reason it is shaped like a c is so you can add the jack with it wired and not have to remove the jack, pull the cable and reinstall the jack. the c part just slipped around the wire. to remove, unscrew the jack cover from the c bar and the bar may fall down the wall cavity if you don't hang on to it. |
