The Robelle Dura-Guard Ultra Winter Cover is an ultra-premium cover for above ground pools. This cover includes a four-foot overlap, making this cover easier to secure to your pool than other pool covers. The dove gray top of this cover is coated with an ultra-premium UV-resistant high-density polyethylene, and the bottom side is black to prevent algae growth. Includes a premium quality binding around the entire perimeter of the cover that prevents against wear and tear, helps keep grommets in place, and adds to the life expectancy of this cover. The Robelle Dura-Guard Ultra Winter Cover features an ultra-premium 12 x 14 scrim (threads per square inch.) This cover is constructed with an ultra-premium polyethylene material that weighs 4.5 oz./yard2. Both the scrim count and material weight are good indicators of the strength of your pool cover. A cover with the tightest weave and heaviest material, like the Robelle Dura-Guard Ultra Winter Cover will last longer than inferior covers. Two premium grommets are placed on center every four feet. With these grommets, you should use the included stainless steel winch and all-weather cable to secure your pool cover. The Robelle Dura-Guard Ultra Winter Cover includes a twenty-year warranty.
