Manufactured in the USA by seasoned pool industry professionals with over 50 years of experience, this SmartLine 33' round overlap expandable liner features a swirl bottom and a 72" height at 20 gauge. Made from 100% virgin vinyl with built-in UV protection, the liner is engineered to resist punctures, cracks and fading. Each liner is hand-folded to allow smooth installation without wrinkles or imperfections.

A gasket set is included to seal all thru-wall skimmers and water return lines, helping prevent leaks.
