Beaded Pool Liners work only in above ground pools that use a bead track to attach the liner to the top of the pool. Beaded liners simply snap down into the bead track or bead receiver that runs along the entire top of the pool wall. Because the Unibead liner is capable of doing the same thing, there is no need to stock both style liners any longer. However we do stock the Doughboy, Lomart and Embassy factory replacement beaded liners. Note: It's very important to measure your pool including wall height before ordering any beaded or unibead liner, and use only the correct wall height for your pool. Using the incorrect height liner can cause unwanted wrinkling.
