Overlap liners are designed to fold over the top of your pool wall and do not require a bead receiver as they are attached through use of coping strips. CELEBRATE SUMMER: Above ground swimming pools offer a great place to gather with family and friends creating lasting memories. Make the most out of this time and do it in style. The Swirl Bottom liner will help you stay and look cool during the dog days of summer. HEAVY DUTY MATERIAL: Made from 100% virgin vinyl, these liners are computer cut and the seams are lap welded for a flawless fit and finish. The Lamiclear technology provides years of protection against abrasion, chemicals and UV fading. This is result of the use of three layers including: An acrylic top coat, UV resistant print layer and the virgin vinyl base layer. A 25-year limited warranty is included protecting against defects in material and workmanship.
