18 x 33 ft Oval Pool Expandable Overlap Liners
Expandable liners are used on Doughboy above ground pools, which have a deep end section. The liner expands to stretch into the deep end area. Do not use an expandable pool liner on a pool not specifically designed to use one.
This page lists 18' x 33' expandable pool liners, and are all overlap style, which overlap the pool wall. This type of liner is draped over the pool wall, centered, and adjusted so the deep end of the liner is in position just off the floor, and clamped or held in place by the installers. As water is slowly added, the liner stretches into place. Adjust the liner as it fills to avoid wrinkles. The Liner can be released when the water is a few inches up the walls and secured with coping strips.
18'x33' expandable liners are quality tested for defects before being packaged. You can count on a durable, quality constructed liner, in a 20 gauge thickness.
