Material Type: Boulder Swirl


Size: 27' (Round)


Features

  • MEASURE TWICE, BUY ONCE Whether installing for the first time, or replacing an existing liner, the Boulder Swirl 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 27' round unibead style liner works with pools with flat-bottoms measuring 54". 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***
  • 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 Boulder Swirl liner.
  • HIGH QUALITY MATERIAL - Swim carefree knowing your liner can tough it out through abrasion, chemicals and UV fading thanks to the use of Lamiclear technology. The layers are made of an acrylic top coat, a UV resistant print layer, and a 100% virgin vinyl base. This material is then welded and cut for a flawless fit and finish. A 25-year limited warranty is included protecting against defects in material and workmanship.

  • Hole in the liner - not seam
Material Type: Boulder Swirl Size: 27' (Round)
Installed new liner last week only to discover a puddle outside the pool several hours after the last water truck pulled away. I paid particular attention to how I handled the liner, and even more attention to not stepping on the liner. After researching previous complaints about the warranty and how this company handles it, I choose not to even try for a refund. The hole was about the size of my pinkie, so yes I have a brand new liner that looks nice , with now a nice new patch. Spend the money and buy a better liner from a reputable company. I chose not to drain my $700 worth of hauled in water to cut a sample out of the liner to send to the company and await a decision from them on whether it was caused by them or me . I know how that would turn out ... show more

  • Nice looking liner.
Material Type: Crystal Tile Size: 16' x 32' (Oval)
This was the first pool liner I installed myself. The liner itself fits good and installs easy enough. The prep work, not so much. I'm totally satisfied with the outcome. The pool itself is 16 years old and this liner will hopefully make it last for another few years. I don't have a clue how long it will last, hence the 4 star rating instead of 5 stars. That said, the package came as promised and in good shape. I was especially happy that the liner didn't have any holes or ripped seams as some have reported. Returning something like this would be a nightmare. ... show more
