I had granite installed and am replacing all the electrical myself. I purchased extenders but they don't seem to be working because the granite was cut too tight. Since all the wires are covered up inside the back of the receptacles do I need to use the extenders? I bought longer screws and it works fine but I was just concerned with the idea that there is nothing surrounding the outlet other than granite and the old box if I don't use the extenders. There is only a slight bit of particle board that shows through on the side. Any thoughts would be appreciated:whistling2:
