Mini-clamps did the job
I used the mini-clamps to secure 18" strut channel pieces as rungs on a crawlway along the roof to the chimney chase. The mini-clamps are precision made, although I found that I sometimes had to hold the adapter insert in place with channel locks while I torqued the set screw in order to keep it (the adapter) from walking out of place. That aside, I'm rating these at 5 stars because they're well made and they enabled me to install the crawlway without having to worry about damaging the roofing.

S5!-N Clamp
Great option for rail-less mounting on nailing strip standing seam. Super fast shipping from Schafer, I am super impressed and have now ordered multiple times from them.
