Does anyone have any favorite tricks for installing outlet and switch boxes in walls destined to be covered in two layers of sheet rock?

We use 4" sq box with a plaster ring.

2 layers of 5/8" sheet rock need a 1 1/4" raised ring

Wood framing or metal? RX or BX/MC?

Nail on boxes can be a pain as the nail bosses can get in the way of the first layer of rock.
We do alot of log homes. In interiors we find a problem even with 3/4" T&G wood where the carpenters have to notch the back side of the boards because of the boxes.

1900 boxes with plaster rings is a no brainer.

AC,

I consider these boxes to be one of the best new products I've seen recently. I'd recommend them for any place where you're not sure what the final wall thickness will end up too. They're great for Kitchens and Bathrooms that might get a backsplash, or Tile, or whatever, very easy to adjust.

As an addenda to Sparky's post, the Arlington extensions as pictured are, to my knowledge, the only ones that are currently UL approved.
They are made by other companies, but don't have the UL.
Bill, very neat box!!...S

I love these boxes, and Blue is my favorite color. They seem pretty sturdy too.

Here's a 2 gang notice the clamp inside that could be used for larger gauge cables.

I don't have any problem using 1-1/2 inch 6/32 screws on back splashes and such.

Sandro,

Having boxes set back that far in the wall isn't against your Canadian Electrical Code?

I use the adjustables Bill posted in every kitchen and bathroom. The only bad part is they only come in 1 and 2 gang.
