Our first summer project was a solar cover holder to attach to the pool. We have never used the cover because when the kids get in to use the pool they can't do anything with the cover. They end up pushing the cover to one side which takes a lot of room. I looked up this project on Pinterest and then made it. Works pretty good.
I added a bar across the middle. This new version holds the cover up better by not allowing the cover to sag through.
Made from 2 inch PVC pipe screwed directly into the plastic pool columns.
