I've seen a competitor around here using prefabricated box support assemblies that consist of a 4Square box spot welded to a short piece of metal stud, they then screw that stud to a wall stud and thats it. Some boxes are an assembly with 3 boxes all spot welded into one assembly with metal studs between each of them. They also use a "pencil rod" material welded to boxes and to angle brackets for supports in ceilings and then use batwings Caddy Kx or K12's to attach cable and raceway to the pencil rod, some cases just zip ties.
Its a fast and cheap install. It looks horrible and takes all the workmanship out of the installation. The inspectors are signing off on it though. Is there anywhere in the code that requires box and raceway supports to be UL listed?

It is fast and cheap while on the site - somebody still had to do all the welding and other fabrication someplace. It is likely still saving something or they would not be doing it. I don't see that it is a problem in general NEC wise. If it is outdoor equipment and welded - it may at very least need to have some added corrosion protection where the original finish was damaged by welding.

I do know it says somewhere that you can not weld metal raceways as a method of supporting them, but not boxes.
