SmartlineSmartline Stone Harbor 21-Foot Round Pool Liner | UniBead Style | 52-Inch Wall Height | 25 Gauge Virgin Vinyl | Designed for Steel Sided Above-Ground Swimming Pools | Universal Gasket Kit Included
Main highlights- UNIVERSAL GASKET SET - The included kit is for the pool’s skimmer and return. This skimmer gasket will work with either standard sized skimmers or widemouth versions. These pieces will help prevent corrosion of the pool wall and should be replaced each time a new liner is installed as they become dry over time which could cause leaks.
- STAY COOL IN THE POOL – Enjoy the warm weather while spending quality time with family and friends. Your backyard pool will surely become the place to be during those hot summer days. Stay cool in more ways than one with the Stone Harbor liner.
- PRETTY PLEASING PATTERN – This tiled bottom in various shades of blue, leads to a marble like tiles. These marble geometric shapes create a simple but classic look. The North American cut material is hand-folded to prevent permanent creasing and excess wrinkling. Before installing, lay the liner out in the sun for a minimum of one hour to warm up the vinyl ensuring it is able to stretch when adding water. The best temperatures to install would be between 70-80 degrees.
- MEASURE TWICE, BUY ONCE – Whether installing for the first time, or replacing an existing liner, the Stone Harbor pattern offers durability while not breaking the bank. Be sure to check the measurements of your swimming pool to assure the correct size is purchased. Pool height is determined by measuring the outside wall from the ground to underneath the top rail. Round pool size is determined by measuring from the center point wall to wall in order to obtain the diameter.
- INSTALL IN A SNAP OR A HOOK – This 21' round unibead style liner works with pools with flat-bottoms measuring 52". For an overlap style pool, simply open up the j-hook portion and slip this over the pool wall. For beaded style pools, use the standard bead after removing the j-hook portion along the score or groove mark. This will leave only the standard bead which is inserted into the bead receiver opening. ***Will not work with Intex or Pop-Up pools***
