I've got a situation where I need to install a single or duplex receptacle outlet in a very shallow depth wall. It's a special situation but I believe I've seen them before. Any help?
Recently did this in an
extremely shallow basement wall (3/4")... 1x3 firring against a concrete wall.
I have a friend who is a wiz with wood and she used a bandsaw to carve 2x4's into blocks the size of a receptacle box plus an additional 1" all the way around. She then carved out the center in the exact shape of the box so it would fit nice and snug. The first one was the biggest pain, but once she had the template she knocked out 6 of these in about 30 minutes.
That gave us ~3" thickness to work with, which was enough for the NM to fit around the corner of the block into one of these:
Still only have 10.5 in3, so next step is to attach WireMold V5751 to the steel box and then tack the assembly to the wood block using GE Silicone II -- there's not enough interface between the WireMold & wood for screws.
Those are 10.8 in3 AFAIR, so that gives 21.3 in3 -- tight, but good enough for wiring 12ga. 3-ways, including the internal clamp.
Once the whole thing was together (including the NM) I used the Silicone II to glue the whole thing to the wall, using some cinder blocks leaned against 2x6's to hold it in place while curing.
The whole thing was a pain, but it worked after some experimentation.
