That's exactly how I interpreted it. That assembly prevents the pipe from moving at the grooved coupling on the main as is required to keep the head within the design criteria.
Just have never been questioned on it and am wondering if anyone else has. And if so, what is the best solution.

That can be 12 ga. wire if you so choose. Look at NFPA 13, 2013 ed., 9.2.3.7 & the Annex material for it. The same criteria goes back two or three editions.

We have sprigs for back to back attic sprinklers running from the main to the peak of the roof and have them supported with loop hanger ring-rod-and threaded fastener. I cannot find anything that requires a listing for this assembly nor can I find any listing for something like this. Any help would be appreciated.
