Box Extenders with Larger, Trimmable Flange
Extends set back metal or non-metallic electrical boxes up to 1-1/2"
Arlington's non-conductive box extenders extend set back metal or non-metallic electrical boxes up to 1-1/2", the easy way! Our box extenders have a slightly larger flange that provides extra device support when the wall opening is miscut or oversized. They accommodate midi and jumbo cover plates, and are trimmable for use with standard plates.
They work with any single gang device and most steel and
non-metallic outlet boxes, providing a level and fully
supported wiring device that's flush with the wall surface.
