Replying to Don;t make rails from PVC

They get ground down and weaker after a couple years of use. I was using mine last night and the rail cracked. one of the screws that was holding the pipe down came up and took out a piece of my edge and made the biggest hole in the ptex. There's a huge part that you can see the core. Also where it took the edge out part of the sidewall (well not really they're fujatives but I dunno what you call it on that) broke off. AHHGG
