Details: Our above-ground unibead liners work as overlap or beaded liners. Unibead liners are easier to install than overlap liners, and they allow you to have the beautiful designer border found only on beaded-type liners. The liner’s j-hook simply slips over the top of the pool wall and hangs straight and securely into the pool. Our unique unibead liners will also fit pools with bead receivers. They are constructed of top-quality vinyl and loaded with u.v. Inhibitors to make our liners last for years and years. Our heavy gauge unibead liners are backed by a 25-year warranty.
