Electrical box set behind sheetrock

Hi folks,

Iím replacing the outlets and switches in our playroom. The existing switches are pretty old. On one wall in particular, two of the electrical boxes are set back from the sheetrock. In other words, the front of the electrical box is behind the sheetrock (see attached pictures). So a good portion of the outlet is NOT in the box. I thought that was the whole point of the box, which is to house the outlet in case there were sparks or anything?

So, assuming this is a problem, how should I proceed? I could rip out the old box, but itís nailed to the stud. Any other thoughts? See pics attached.

thanks!

If a box extender does not solve the problem, you cut the nails with a saw and install an old work box.

Thanks guys, you rock! The metal one that you linked appears to be adjustable, while the plastic ones do not. Maybe Iíll buy all of them and see which one works best.

In the original pictures I posted, the second picture that has the black outlet looks like it will be fine with a typical extender.

The outlet in that first picture has a bit of a strange electrical box because the opening for the outlet is not the perimeter of the metal box, it is set in maybe a quarter of an inch. Hopefully that makes sense.

The first box is a 4" square (1900) box with a mud ring on it. This type of box allowed for extra room for wiring. The mud rings are available from 1/2" to over an 1" but can't be changed after the sheetrock. Box extenders don't work well in those boxes.

Thanks, any thoughts on what to do with that first box then? Maybe cut it out with a Dremel?

If one of those short spacers are too big then you'll have no choice but to use one of the plastic extenders. That would be some pretty tough metal to cut out.

OK, after about 2 1/2 hours I finally finished the first outlet in my original post. I wound up having to cut the sheet rock a little bit to fit the box Extender, used the largest extender, as well as a few spacers, and eventually got it. Thanks for the help. Two pictures below of the finished product.

Now I am on the second outlet, which is a little different. The box extender fits around the electrical box pretty easily, but there is a bit of a gap at the bottom. See attached picture for gap between the electrical box and the blue box extender. Should I be concerned about this gap, or does it not really matter? I see that the box extender works well to make the outlet sit flush with the sheet rock, but in theory it kind of makes a gap as pictured.

Turn the extender around or use an Arlington BE1.

If the box is set back by 9/16" or more the following metal ring spacer works well:

These are the ones I use. No metal near the screws.

I have similar issues with many electric boxes. Can a plastic box extender be used to extend a metal box?
