I found out about the clips you install over the pool walls to change a lap pool to accept a beaded liner. I hope this is correct, or is it just to enable to use j hook liners. What I would like to know is, if it does change the lap pool liner to a beaded liner, what would be the correct size beaded liner. If you have a 52 inch wall pool and add the clips what height beaded liner do you buy? And too are these type clips ok to use?
