This small investment will add years to the life of your above-ground pool liner! Place pool cove around the bottom, inside circumference of your pool wall before installing your new liner. Pool cove will help prevent excess stretching, premature wear, and wall collapse by deflecting water pressure that could otherwise push the liner underneath the pool wall. Peel-&-stick pool cove has an adhesive backing that allows for installation in seconds. Available in 48" sections.
