It is amazing to me when I have to explain it to licensed workers.

It also amazes me how stingy people will be with supports when the supports are almost always the cheapest part of the raceway system.

Along with supports being cheap IMO they have a very direct influence on how long the work stays looking good and stays safe and serviceable.

I agree the unsupported pipe in your drawing meets code but at 9' I can say I would never leave it unsupported.

Make that piece less than 2' and I might let it go unsupported.

Basic rule for me with supports is the more the better, no such thing as to much support. :D

Edit: To go on, ;) you can get 3 grades of 1 hole pipe straps, I never get the lightest duty, most times heavy duty sometimes the medium grade.
