The 18 foot round Willow Creek pool liner is designed for above ground pools with a 54 inch wall height. It features a Uni-Bead design and is suitable for use in various outdoor settings. This liner is a single pack item and is intended for installation in pools of the specified dimensions. I bought this last year thinking we were going to replace the liner this year.
We have decided not to keep the pool. I Can't remember much about it when I bought it you can see the receipt what I paid for it. You will have to try to research the number on the box and see. It has never been out of the box.
Any question ask I will try to answer the best can.
