In The Swim LI1848SB 18' Round 20 Mil Overlap Liner for Above Ground Pools - Swirl Bottom - Fits 48/52 Inch Walls

This In The Swim LI1848SB overlap pool liner is made for 18' round above ground pools and features a decorative Swirl bottom. Constructed at 20 Mil thickness, the vinyl resists UV fading and chemical deterioration to extend liner life. The overlap style hangs over the top of a 48" or 52" pool wall and is held in place with Pool Coping Strips (not included). The liner is manufactured with extra material to accommodate common 48" or 52" wall heights; any surplus can be trimmed away to achieve a precise fit.
