outlet box extenderI got a call from a friend with an electrical problem. He was having granite installed and chose to run it up the backsplash. The problem was that the granite was ¾” thick and when he went to install the outlet covers back on, they didn’t reach, as the outlet was recessed in it’s old location. The answer is a box extender, also known as an extension ring.

An extension ring allows you to extend the junction box to meet the new surface of the granite, in this case. You can also use an extension ring outdoors if, for example, you were adding conduit to a run.

The box extender is simply a ring that extends the junction box. Turn the power off to the circuit and unscrew the outlet or switch. Gently pull the outlet or switch slightly away from the box and maneuver the box extender over it. The box extender gets secured to the junction box, and then the outlet gets screwed to the box extender. There are holes in the box extender for this. Once you have the outlet screwed to the box extender, you can install the outlet cover over it and everything will be flush with the surface.
