This rugged mesh cover makes spring clean-up a snap. The secret to this unique cover is the tightly woven scrim that holds together insuring that no gaps or holes develop. Rugged mesh allows only rain water and very fine silt to pass through. Since the cover is made of mesh that is very lightweight, simply lift it off in the spring. No heavy water to lift off or time consuming cover pumping. Simply remove the rugged mesh cover, vacuum up the fine silt and open your pool. Since our scrim is so tightly woven, the cover allows almost no sunlight through and ensures an algae-free pool in the spring. Our rugged mesh covers are made from tough U.V. protected woven polyethylene that is strong enough to handle ice, snow, sleet and high winds. All Arctic Armor Rugged Mesh covers have a 4 ft overlap and include a cable and winch tightener.
