John I have never seen a UL listed strut clip.
There are some UL listed strut products but they have to do with using strut as a raceway.
Reno, IMO you can not enforce workmanship, that is like enforcing good taste.
It is far to subjective of a subject.
Yes I see that strap in the photo of a poor workmanship. But I can not say it is any less safe then a mini supported by a rod.
