21 ft Round Pool Expandable Overlap Liners
Our 21' round expandable pool liners are used on pools made by Doughboy, designed for an expandable pool liner, which stretches to fit a deeper center section.
Some wrinkling may be unexpected using expandable pool liners, depending on the slope of the floor, and the stretching of an expandable liner.
Measure your aboveground pool, to be certain that a 21 ft. round liner will fit your Doughboy pool. Do not use an expandable pool liner on pools not designed to use this type of expanding or stretching pool liner.
