Horizon Ventures HV-POOLCOVE 48" Peel-N-Stick Above Ground Pool Cove - This 48" Peel-N-Stick Above Ground Pool Cove creates a uniform transition from the pool wall to the pool floor. It is for new pools and liner replacements. Unlike sand coves, this cove will not wash out. Coves made of sand can wash out and create liner failure. The installation is easy. Simply peel off the clear backing strip and stick to the pool wall.
