Hey guys I've been posting here for a few days, went to take out the pool today and couldn't really find a model number on it. They said it was 15 yrs old, and the metal has a fake wood grain pattern on it. It's a 15x33x4ft AG and the liner was the type that fits down in a rail and clipped in like a tonneau cover for a truck. My other question is, would it be possible to use an overlap liner? When I got there, they had several sections where the liner had come out of the groove in the top trim piece, so I'm not sure if I like that style or not. From the pictures I've seen of the overlap liners, there's nothing between the metal and the rails that hold the overlap liner in place. Just curious. It would probably help to have a model number/ brand name to go with the pool, might be able to get parts and the correct liner for it. Let me know if you guys know how to determine what kind of a pool is.
