Hide device wires or wall box edges with 3-gang oversized outlet switch plate depth extender ring. 1/8" extension gaskets will fill holes in sheetrock around the box as well as create a deep wall plate. These jumbo three-gang spacer gaskets cover up an ugly gap around protruding junction box in shallow exterior walls where you can't install a deeper box. They also fill the slot caused when modern devices are too bulky to make contact with the wall. Great solution for creating a finished edge when installing new deeper dimmers, timer controls, or other big electrical devices.

Created to use with our triple gang jumbo faceplates, but they still can be used with other 3-gang covers for most electrical switches, dimmers, timers, outlets, etc.

  • inner cutout 4.25" H x 6.06" W

    Fixed my problem

    This totally fixed my issue with the box being too far out from the wall. I put this frame over the box and them my switch plate cover and it worked like a charm. No gaps!!!

    Worked perfectly

    Replacing an electric box, and for whatever reason the old face plate was about 1/8 to 1/4 wider than the current box, so there were gaps around the face plate. This oversized switch plate extender worked perfectly. Arrived when it should, sturdy, super easy to install. Perfect, couldn't have asked for more.

    Perfect Fit

    Can't believe you cannot buy these at the hardware store. This was the perfect product to surround a 3 outlet box that was crooked in the wall. Wish I could upload a picture. The fit and finish are 2nd to none. The final install looks perfect.
