I have a 30 year old above ground pool, I do not even know the manufacture and need to replace a few top caps. I would buy a few, new or used but I have no idea how to id them. I looked at the numbers inside and they were no help. The pool is on its 3rd liner 2nd filter, 2nd deck and I even moved the return line due to rust (hayward above ground light is bigger than a return fitting).
Any ideas you have would be great
Here is a pic to help, if anyone has any ideas i can take some better shots
