Double drywall & Electrical boxes?

post #1 of 16
Thread Starter 
I am doing an electrical rough in for my HT and I was wondering how to set the boxes if I am going to use 5/8" & 1/2" drywall? Do I use 1" or better plaster rings for the receptacles, then what about the light switches and luminaries? I have done a couple of searches but nothing evident seems to come up. I have also viewed hundreds of threads of members who have done double drywall and this is never addressed.

thanks
Brian

Carlon makes an adjustable box. It just attaches to the stud and then has a screw that is accessable on the front even after you drywall that moves the box in and out up to about 1.5" depending on the direction you turn the screw. They are great!

What Mike said. They sell single gang and double gang adjustable Carlon boxes at Home Depot.

They look like this:

You didn't mention if you were going to be doing wall treatments and how to deal with that thickness. That was discussed yesterday here:

FYI. Home Depot is no longer selling adjustable Carlon's. You can still purchase at Lowes...

I used the Arlington box extenders seen here. I also used some of the adjustable boxes that were previously mentioned. Ultimately, I liked them both equally, so you can try both and see which you prefer.

I bought mine just last week, so perhaps this varies from store to store. They have them at my local store for sure.

Are you sure? I thought HD stopped selling small boxes of galvanized roofing nails as I could only find the 25 pound pails and I need maybe 2 dozen. Then I go in two weeks later and they have almost a whole shelf of them in 1 pound boxes in every length imaginable.

The problem is, even if you ask, the "helper" won't know and just tell you "we don't have/carry it/them anymore."

There are also PVC electrical box extenders as well. It basicly inserts into a standard box. You can slide it in and out and fix it in place with a set of screws.

Here's the product info I got off of the package.

Manufacturer: Carlon
Item description: BX1EXT-CRD
UPC Code: 034481137634

Home Depot's in-store stock is very much a regional issue (and even an individual store issue). The stock in one "area" can be drastically different from that in the next region, and there are also wide variances depending on the size of the stores. I had a lengthy discussion of this with two of their assistant managers a few months back, when I noticed that one of my area stores carried all of the plastic (Carlon) electric boxes, and another carried none of these. Not one.

In this case, it was because one "region" is defined by Cook County and Chicago, IL, which states that everything electric must be in EMT conduit (no Romex, for example), and that all electric boxes similarly must be the metal type. Less than five miles from my home, though, one passes into Will County, which frowns on the EMT stuff, and utilizes the plastic boxes for outlets, junctions, etc. One can walk into my two closest stores, and when it comes to electric and plumbing, one might have a hard time believeing they were in the same chain.

I also learned that the "larger" stores carry a lot of stuff which the "smaller stores" will never, ever stock. In such cases, when it comes to the regular on the shelf stuff, the smaller stores usually maintain that they cannot even get these items (since they are not truly "special order" items listed on their computers.) I learned this when I wanted a particular item to cut EMT conduit at one of the Cook County (smaller) stores.

This may also be why Home Depot's website does not really show very much of their "stock" at all. Very little, in fact. Their main competition "Big Blue," or Lowes) seems to show about 60 to 70% of what is typically carried in their stores. Home Depot's website does not seem to have much of a catalog for their stock at all.

Hope this helps,

Yes, this is so annoying. I can find next to nothing I'm looking for on HD or Lowe's websites. I'd love to do some of my looking around online rather than driving all over town and walking the isles.

This is all very true. The websites for these stores are just awful. I was just looking online for some folding table legs for another project which folks say can be found at any Home Depot, but definitely not at mine. I didn't get to Lowes - I just skipped to my local specialty hardware store and got them there.

The regional differences and overall insufficient website details make any kind of advance planning for purchases quite difficult.

Try the commercial Home Depot site:

hdsupplysolutions.com

They have free delivery for larger orders.

Metal boxes seem more popular around here.

You could just mount the box so that the face of the box is 1" out from the stud. (in my case, I used double layer 1/2" drywall and greenglue in my HT/media room. I placed a scrap piece of 1/2" plywood along the stud while nailing the box in place. You can bend back or dremel off the tabs that used to go flush with the wood stud after it's nailed in

It is a little harder to rotozip out the openning on the inner layer of drywall, but it gets better with practise. You can save the $4/outlet instead of buying extenders in addition to boxes.
