    Default Extender Ring for Old 3"x2" metal electrical box

    Can anyone direct me to an 1/2" extender ring for an undersized (3"x2") metal electric box?

    I'm demolishing an old bathroom and converting it to a closet. When I pulled the sink vanity I found the dreaded buried electrical box behind. I expected that this box was de-energized because the wires were not capped, just wrapped with a sparse piece of electrical tape. The box was not covered with a fire resistant cover, just snuggled up to the wooden vanity. The box didn't even extend out to the edge of the drywall, it was recessed flush with the original wood plank wall. Much to my surprise I found the wires hot! I've been living in this old log cabin for near 20 years and still finding scary stuff...

    Anyway, the extender rings in my "inventory" are all for the 4" boxes and even the more flimsy tapered versions will not fit in the 3" high box. I have installed proper wire caps on the wire tips and would like to safely close this box up. I have no problem with having a blank junction box cover on this wall visually, so no reason to try to pull it out.

    Anyone have a source for a extender ring and wall cover for the 3"x2" box?

    It's a common product at most big box stores.
    This one is from HD. it's good for up to 1.5 inches.

    Or you could just remove the box (beat it out with a hammer and heavy screwdriver) and put in a newer 4x2 old work box. This will most likely give you more cubic inches and a bit more wire length in the box. Don't know if you need to use this box, or you are just going to cover it.

    It doesn't look like it would be difficult to remove as it appears to be installed using finishing nails into 1x8 T&G around the perimeter. However, the wires were trimmed back, not extending more than a 1/2" or so beyond the wall plus it is the metal sheathed wire - having the metal casing apparently affixed to the back of the metal box. I was thinking that it would be more expedient and effective if I could close the box as it exists. But I may yet take that route - I tend to take the long road more often than not.

    I will look for that extension sleeve that I presume is "short" in height. I do have sleeves that look like the one in the chrisb's photo but they are too tall and the holes do not match up with the metal receptacle. The holes appear to be approximately 3 1/4" breadth.
