The 12’ Round Vinyl Overlap Liner Blue Mount Royal is a durable liner designed for above-ground pools with 52” high walls. 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 Blue Mount Royal print adds aesthetic flair to the pool floor and the vinyl construction offers UV resistance that helps extend the liner’s lifespan by reducing fading and cracking caused by sun exposure.
