Overlap pool liner coping strips are plastic, non-corrosive clips that hold your pool liner in place on the pool wall before you reinstall the top rail. You should replace the coping strips on your above ground swimming pool every time you replace your overlap pool liner. Throw out those old, worn out coping strips and replace them with new ones to your pool and prolong the life of your new pool liner. Not replacing your coping strips increases your risk of damage to your new liner. Our coping strips may come in black, grey or white based on our supply.
