18¡ä Round Boulder Swirl Overlap Liner

The Boulder Swirl 20 gauge overlap liner is made of 100-percent virgin vinyl material. Overlap liners are the most economical liner option and are easy to install. Overlap liners attach to the pool wall with coping strips that hold the liner in place. Coping strips are pieces of plastic that snap on to the top rail of the pool. Because overlap liners don’t lie as flush with the pool wall as beaded or unibead liners most overlap liner designs are limited to solid colors and uniform patterns.
