The Economy pool cover is a solid winter cover. Solid pool covers do not allow water to pass through their material. This winter cover is intended to be used during the off-season. Please order by your pool size, as the overlap goes beyond the pool size listed. This cover includes a 3 ft. overlap. If you have a very large top rail, please consider a larger pool size. The Economy pool cover has a 7 x 7 scrim. Polyethylene weighs 2.2 oz./yd2. The blue topside of this cover is coated to prevent damage caused by the sun's ultra-violet rays and the bottom side is black to prevent non-living organic matter. 2 grommets are placed on center every 4 ft., with these grommets, you should use the included winch and all-weather cable to secure your pool cover.
