Just curious what others have done? On a cmu masonary wall we have 7/8" hat channel going up with 5/8" drywall to cover on a buildout. 1 1/2" total and we need to install receptacles on these walls. What type of boxes have you used so that this is a flush installation?

Shallow 4 square boxes are 1 1/2" deep so don't think that will work, looking for what you've done (other than put it in the masonary)

Aside of knocking some block out behind, I would say some kind of surface mount install.

The shallow 1 1/2" cut-in boxes would likely fit depth wise, but are damn near impossible to get a device in with a 1/2 fitting in the top.

As was said before, blow out the block behind the boxes if you are using 4" square boxes. If the customer/GC doesn't like it, tell them to build a real wall for you to work with. You will be faced with the problem of mounting the box as well. Bline brackets across two channels works. The standard bar hangers are out becaues they "steal" space behind the box and will not sit back far enough. If you can feed each device from the top individually, I just use a 1-1/2" deep, single gang handy box anchored to the block with plastic anchors or tap-con screws. They sit flush with the drywall.

How many conductors can you put in it?

No more than one cable I bet.
The cable doesn't do any good without a device :)

These are sometimes used in these situations but (I think) they are not legal with a device.

One time on a remodel, I came upon a solid/poured block wall with 3 of these existing/wired and was able to get receptacles installed along with two 12/2's .:jester:

They make XXXL sized single gang plates too.

I remember a couple of years back I was cutting a box into a kitchen island. Had tried using a Fein to do the job and all it was doing was burning the wood. SOB skipped on me and marred the wood up.

I had to use one of those super jumbo cover plates to cover my boo boo. SOB was HUGE. Looked like hammered **** to me.

No one else noticed. :laughing:

Thanks all for suggestions. Just a note this is in a brand new ground up building. Maybe we should have put them in the block but we didnt so was just trying to get ideas of what everyone had done. Keep the ideas coming if you have them

print out some nice quality pictures of wall receptacles with trim plates.

tape them to the wall where they are required per the prints.

hope no one notices prior to cashing the check.





I like pictures.
