WINTER PROTECTION. Top Choice cover series is the perfect choice for providing protection against sun, snow, ice and wind for your above ground pool in areas of the country with harsh winter conditions and inclement weather. This solid cover is crafted from a woven, laminated polyethylene material that keeps dirt, leaves, and branches from decaying in your pool all winter. Every Pool Cover Choice winter cover is treated to protect it from sunlight degradation. SPECIFICATIONS- This round cover fits a 21 foot pool size and the overall total dimension of the cover is 25 ft which includes a 4’ overlap. The scrim count (the number of fibers used per square inch in the fabric's weave) is 12 X 14 with a material weight of 4.5oz/yd2. These specs give this cover extra strength and durability. For additional protection, each cover has the thickest black underside coating in the industry. EASY TO INSTALL & SECURE - This cover features a 4-foot overlap (extra material beyond pool size), making the cover easier to install. Secure the vinyl-coated steel-core cable through the reinforced metal grommets and tighten with the specially molded metal winch. The winch turns smoothly making it easy to tighten the cable securing your cover in place. BUYING TIPS: When ordering be sure to order by your actual pool size.

For pools with an extra-large top rail of 10” or more please order the next size up.
