|Riser between garage and attic
|Conduit and mounting materials
NEC article 352.30 requires supports within 3' of each termination and least every 6' so I went with a bottom, middle and top support after cutting down the conduit to 90" (7'6").
|Access hole in closet
Holding the elbow base against the top strut, I located and cut a 3" diameter hole in the drywall using the elbow as a template. I then ran the elbow through the hole from my access hole in the side of the closet for final test fit.

I reached through the access hole and attempted to install the other two clamps and found that the offset from the wall caused the clamp to not quite close. Longer bolts (2 1/2") fixed the problem allowing me to support the conduit in the upper 2 locations.
