I like to use strut to fasten to thin siding. Even if you can't get at a structural member, you have more screws for support - as many as you like, I guess. If the conduit is on deep strut and the box on shallow strut, the conduit lines up with the threaded hole in a box better than I can bend an offset.

I don't really like the look of strut, but it does look nicer than conduit falling out of the straps.

twh gives me a good idea on this....
You can usually tell where the studs are easy on this type of material, since the metal sheeting is already screwed to it... the situation being that the studs are going to be in the low spots of the sheet metal design.... a small piece of strut mounted vertically in the low spots with the studs should yield a solid support system [Linked Image] a couple spring nuts wo mount the boxes (raintight w/ GFI, of course) 86 the MC cable, split elbow & anything else that belongs inside, a pull elbow, wp blank w/ 1/2 in KO, LB & threaded chase nipple... I think I remembered everything [Linked Image]

I have found the reason why outlets should be installed ground up!
Imagine a 1/2 plugged heater with ground prong, plugged into an outlet ground down. Drop a penny in between the prongs and tell me what happens. Then do the same with ground up. Gravity is the reason the plug should be ground up. [Linked Image] [Linked Image]
