if you're running EMT 1" and smaller on concrete with 1 hole straps do you always use a clamp back or just with rgs? thanks
 
If you use them (AKA back straps) then you can go straight into the box without needing a box set.
 
We only use clamps and backs with rigid. For EMT we would use a regular one hole strap with the conduit tight to the concrete.
