Arlington BE1R Ceiling Box Extender F93334

Arlington’s 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 single 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.
