Throw out those old, worn out coping strips and replace them with new ones. These plastic, non-corrosive clips hold your liner in place on the pool wall before re-installing the top rail. Brand new Overlap Liner Coping will help insure a firm, proper liner installation. Overlap Liner Coping are used on most above-ground pools. An overlap style liner hangs over the top of the pool wall and is visible on the outside of the pool wall. The liner is secured with plastic liner coping strips, then covered up when the top channel and Top-rail covers are reinstalled. These coping strips are sturdy, yet flexible, and can be cut to required lengths.
