SmartLine 18' Round Overlap Above Ground Pool Liner — Boulder Swirl, 48"/52" H, 25 Gauge

SmartLine 18' round overlap liner in the Boulder Swirl pattern — a 25-gauge replacement sized 48"/52" high for above-ground pools. Manufactured in the USA by pool industry professionals with over 50 years of experience, this liner is built from 100% virgin vinyl and features built-in UV protection. The durable material resists punctures, cracking, and color fade, and stands up to harsh pool chemicals and prolonged sunlight exposure in temperatures from -50°F to 130°F. Each liner is hand-folded to reduce wrinkles and make installation easier. A gasket set is included to help prevent leaks and fits all thru-wall skimmers and water return lines.
