Liner Life 21R Solid Black Geotextile Liner Pad — For 21' Round Aboveground Pools

Liner Life geotextile pad designed to protect aboveground pool vinyl liners from damage caused by grass, roots, rocks and other sharp objects. Constructed from high-quality, durable geotextile material in a solid black design. Helps prevent "footprints" from forming in the sand base beneath the pool liner. Manufactured to fit most popular pool sizes and shapes — round, rectangular or oval — so you don’t need to measure, cut, and tape like you would with foam padding. Model: 21R.
