TIGHTER WEAVE: 10 x 10 Cross stitches per inch solid covers. In-Ground covers are 5 feet wider and longer to accommodate water drop. 12-year warranty, 3 years full. Full coverage on manufacturer defects only. Green Top, Black bottom.

When you purchase the In-Ground 12 Year Warranty Pool Cover with the water bags, you will receive the 20G Double Chamber Water Bags.

Our Exclusive Non-Tearing Weave: Our triple-laminated solid covers are woven extra tight to resist tearing and coated with an extra-thick, non-rotting polyethylene for durability. Lightweight and easy to work with, they protect your pool from dirt, leaves and contaminating sunlight. They are the perfect size to accommodate water drop without creating extra slack that could result in wind damage. Choose the weave that best accommodates your winter conditions and your budget. Unbeatable value. Compare our prices to any competitor and SAVE!

All-Weather Galvanized Grommets—Grommets are placed in each corner.

Large Piece Construction and Poly-Strength Double Stitching for Extra Durability—Our triple-strength covers are made with large continuous pieces and have fewer seams than standard covers. Pieces are assembled with weather resistant, poly-strength, double stitching for greater durability.

Heavy-Duty Triple-Laminated Built in layers for extra strength—Doheny’s has the strongest winter covers in the industry. Manufactured with three, weather resistant layers, our covers last for years and protect your pool in temperatures down to -50F.

Black Laminate Bottom—Resists Algae Growth Laminated bottom layer resists algae growth by blocking out the sunlight algae need to grow. Makes spring opening EASY!

Keep your Water Bags securely in place with our Heavy-Duty Water Bag Loops— Securely stitched approximately every 4 feet around cover perimeter, loops help keep bags firmly anchored preventing roll away.

Does your inground pool have built in steps? Order a larger cover! Customers with pool steps which extend beyond the rectangular shape of their pool should order a cover that is larger than the size of their pool. For example, if you have a 16 ft x 32 ft pool with a 4 ft built-in end steps, order a cover to fit a 16 ft x 36 ft pool.
