I am in need of a new liner and don't think mine is a beaded liner. I know it isn't a over lapped one. What is mine called. The top of the liner pushes into a grove that is made into the top rails of the pool. The top of the liner does not go into a receiver thing that sits on the top of the pool. The top of the liner does not touch the top of the wall at all. Does any body know what this is called.
Thank you
