I am putting some plywood sides on my trailer, and will use two-hole pipe straps to secure (see pic). I’d like to place some sort of rubber or neoprene or (open to suggestion) padding or protective collar around the pipe where clamp is placed to protect it from having the paint scratched off, but am having an issue finding something I can use at Lowes Depot. The right solution will be some sort of tubing made from appropriate material (UV resistant is good but not high priority) that either comes in ~1 inch lengths or can be cut down to. The pip is 1.5 inch OD, so that needs to be the ID of collar/padding tube. OD of collar needs to be close to 2", i.e. the next size up in pipe strap size.
Any suggestions on what to use and where to source?
