The 15’ Round Vinyl Overlap Liner Blue is designed for above-ground pools with wall heights ranging from 48” to 52”. The overlap design is installed by folding it over the top of the pool wall and securing it with coping strips, making it a practical choice for DIY installation. The vinyl construction offers UV resistance that helps extend the liner’s lifespan by reducing fading and cracking caused by sun exposure, while the smooth surface is lightweight and easy to clean.
