  • 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. Oval pool size is determined by measuring from the center point across the longest and widest ends.
  • PRETTY PLEASING PATTERN - Blue rocks top the swirling water backdrop with the Boulder Swirl pattern. 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.
  • NO TROUBLE TO INSTALL - Overlap liners are draped over the walls of the pool during the installation process. Once the bottom seam is even near the cove, the liner is ready to be secured. This material is held in place through the use of coping strips prior to putting the top rails back onto the pool. Bead receivers are not needed for this type of liner. The liner is made to work with pools which have a flat bottom and wall heights of 48” or 52”. ***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 aboveground 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.
  • 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 wide-mouth 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.

Liner Knowledge

Comparison of Smart-Line Liner against other brands shows that liner does not fade do you sunlight

SmartLine liners hold up better than many alternatives thanks to an acrylic coated layer on top of its virgin vinyl. Prevent liner fading due to chemicals or UV rays and keep the vibrant colors of your swimming pool liner.

A stop-watch with a one-minute clock face plus a sun

SmartLine liners come folded to prevent creasing. Lay out in the sun for at least 1-hour prior to installing to ensure the material is able to stretch when adding water.

Don't Forget To Protect Your Liner!

SmartLine pool liners are very durable, but we suggest protecting your new purchase with a pool pad from Rhino Pad.

Rhino Pad is made from a special cloth fiber that is soft and durable. Defend your liner against cuts and punctures from rocks, roots, grass, glass and other harmful debris found on the ground. It will provide a flat base that gives an extra layer of armor for your swimming pool floor bottom prior to liner installation.
