Have you had trouble with your clamping of the spec system comming loose and the pipes falling down?
Answer #1: Weld the pipes
Answer #2: So you’re at the track and it catches comming off the trailer or on track. No welder is close by.
Do the Matt Thornton trick: cut slots into the pipe so that the clamp can clamp.
Thanks to Matt for the idea and the solution. ( Actually it was his problem, I’m just passing on the tip.)
