They use mud rings for the drywall thickness that they will be using, they
mount the box flush with the 2X and then the mud ring is the right depth,
then the drwaller uses a zip tool to route out just outside of the mud ring
and the drywall fits snug against the wall. Simple as that.

Hello:

Was wondering how in new house construction they line up the front of
the electric (for the outlets & switches)gang boxes with the front surface
of the plaster board.

Just curious how it is done so neatly, usually.

Guess it would be hard for anyone to explain in words.

Is there, perhaps, a web site that has some pix showing it being done,
etc. ?

Thanks,
B.
