Reference picture below.
The electrical boxes for the switches can be adjusted in/out for different thickness of drywall.
I want to run conduit from the 2-gang switch box though the top-plate and into the attic for about 3 feet. The reason is so that I can come back later and run NM cable to the switch box. The conduit must allow the box to be adjusted in/out to meet the thickness of the drywall or other wall covering.
- Does the NEC allow this?
- If so, what options are available?
I am undecided on the wall covering at this point. At least 5/8 Type X Drywall. Had considered maybe 2 x 5/8 Type X Drywall for sound.
The box is Arlington Industries FA102:
