We moved into a house a couple of years ago with a pool. We had someone maintain the pool and this year I decided to do it myself. Looking through the shed, I found some pool poles and was hoping to use them since they looked like they were in good shape. One of the poles has a metal piece at the end of it with a screw (picture attached). I tried researching on the internet how I can get attachments to it but could not find anything. I was wondering if someone can explain how this pool expands.
Another pole's had a plastic cam lock that cracked. I saw on the internet replacements for the cam lock but was wondering from other peoples experience if it made sense to replace or just buy another pole?
