I had a new trampoline pull out of the track on my 6.0 recently - turned out that the bolt rope was not stitched in place and had backed out when I installed it. It was enough to get the trampoline started out of the groove and a lot came out at once (fortunately I was on dry land at the time!). Before I figured out exactly what happened, I thought about putting a UHMW (soft plastic) rod in place of the bolt rope - has anyone tried this? I wonder if it will accelerate the wear on the trampoline.
