The 18’ x 33’ x 52” Oval Liberty Tile Unibead Above-Ground Liner is a standard-gauge vinyl liner designed for above-ground pools. Its unibead attachment system allows the liner to be installed as either a J-hook or a beaded liner, providing flexibility for different pool configurations. The material is made from 100% virgin vinyl and includes protective treatments intended to reduce wear from UV exposure, pool chemicals, and temperature changes.
