@BigMike55 to make your life easier here’s a tip I wish I thought of the first time I did this.
I measured the lengths from 8’ft sections and drilled a hole the same diameter as my tent’s poles at the “cut point”. A simple cut later I have 2x perfect semicircles which would mount!
I didn’t add anything to prevent slip but I will next rebuilt. Looking into anti slip coatings on the cheap.
