How to use an electrical box extender if you are installing wood, stone, tile or any other material to an existing wall. For a better look and for safety you need to bring the outlets and switches out to meet the face your new wall material. There are numerous ways of accomplishing this, partially depending on the material you’re using.
Using a combustible material such as wood or paneling you must use an electrical box extender. The extender will provide protection from a potential fire caused by an electrical short or loose connection.
Although, not required for noncombustible material, it is always best to use a box extender to close the gap between the existing box and the new materials surface.
If your existing electrical junction box is metal, you can purchase a metal box extension. You could use a plastic one, provided the screws go through to the existing box.
One critical point is to cut the hole in your new material the correct size. The tabs on the extension need to sit on the surface of the new material.
While extensions are good, They are not my preference. If you’re covering the wall anyway, I prefer to open it up and install a new adjustable box. Check out the Next Page to see how to do this.
