Arlington non-conductive box extenders extend set back metal or non-metallic electrical boxes up to 1-1/2 in, the easy way. They work with any 1-gang device and most steel and non-metallic outlet boxes and provide a level, fully supported wiring device that's flush with the wall surface. In steel boxes they prevent arcing and shorting by creating a barrier between the box and device screws.
