Robelle 3718-4 Pool Cover for Winter, Supreme, 18 ft Above Ground Pools

The Robelle Supreme Winter Cover is a heavy-duty, UV-resistant polyethylene solid winter 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. Please order by pool size, as the overlap goes beyond the pool size listed. If you have a very large top rail, please consider a larger pool size. The cover should be able to comfortably float on the pool water without excessive stress. The top of this cover is green, and the bottom side is black to prevent algae growth. The Robelle Supreme Winter Cover features a heavy-duty 12 x 12 scrim. This cover is constructed with a heavy-duty polyethylene material that weighs 3.26 oz./yard2. Both the scrim count and material weight are good indicators of the strength of your pool cover. A cover with a higher scrim count and heavier material, like the Robelle Supreme Winter Cover, will last longer than inferior covers. Two grommets are placed on center every four feet. With these grommets, you should use the included winch and all-weather cable to secure your pool cover. The Robelle Supreme Winter Cover includes a twelve-year warranty.
