This electrical box extender provides a simple solution for electrical boxes installed too far behind the finished wall surface. It extends the box by up to 1-1/2 in (3.8 cm), allowing an outlet, switch, or other wiring device to sit level and flush with the wall.

Made of heavy-duty, non-conductive plastic, this electrical box extender helps create a protective barrier between the wiring device and a metal box. It also supports and stabilizes the device for a straight and secure installation.

This single-gang box extender works with most metallic and non-metallic outlet boxes, as well as 4 in (10.2 cm) square boxes fitted with a single-device plaster ring. It can be trimmed when less extension depth is required.
