Arlington’s non-conductive box extenders extend set back metal or non-metallic electrical boxes up to 1-1/2 inches the easy way! They work for any single gang device and most steel and non-metallic outlet boxes – providing 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.

The BE1X, has a slightly larger flange that covers mis-cut wall material and accommodates midi or maxi cover plates.
