These high quality liners are designed to fit above ground pools with dug-out hoppers. Hopper Liners differ from traditional
expandable liners in that they are tailored to fit specific dimensions. Hopper liners are not meant to 'stretch to fit' like standard expandable
liners. Rather, hopper liners are installed according to a 'dig sheet'-- a special diagram detailing the exact dimensions to dig the hole during
pool installation. Each hopper liner is made to conform precisely to the specifications of its corresponding dig sheet. Uni-Bead construction.
