Product description QH.HOME 21 Ft Round Winter Pool Cover with Fast Tightening Patented Ratchet, Solar Pool Covers for Above Ground Pools, One-Piece Tear Resistant Swimming Pool Cover Protector with Upgraded Ultimate Windproof 【Find Your Perfect Fit】Ensure optimal coverage by selecting the correct size for your pool. This cover is ideally suited for 21FT frame pools and 18FT steel frame pools. (Important Note: Steel frame pools typically have wider edges (6-10 inches), requiring you to choose a cover size larger than your pool's water diameter). Always measure your pool's outer diameter before purchasing and consult our detailed size chart based on your specific pool type. Shop with confidence knowing you're covered by our free replacement or refund policy. 【Exclusive Patented & Easy Installation】Experience effortless installation and superior stability with our exclusive segmented drawstring and ratchet adjustment. The 21 ft winter pool cover achieves a 360° custom, snug fit around any pool edge in just two simple steps: 1) Unfold & Cover, 2) Adjust the bottom ratchet tension. Engineered for extreme weather, it's laboratory-tested to withstand winds up to 100 mph (UL wind tunnel certified). 【Unibody Tear-Resistant Design & Superior Protection】QH.HOME 21 ft Round Winter Pool Cover features military-grade, tear-resistant Oxford fabric, independently tested to withstand 330 lbs. Its seamless unibody design prevents edge cracks/tears, ensuring long-lasting debris and weather protection while blocking water seepage—keeping your pool fresh and extending its life. Ultimate defense, hassle-free savings. 【No De-silver or Discolor】 Made with original yarn UPF50+ certified fabric, this cover blocks 99% of damaging UV rays. Its high-temp PU coating (rated to 230°F vs. average 180°F) effectively prevents the common issues of delamination ("de-silver") and discoloration. Backed by a 3-year fade & delamination warranty, it saves you money and hassle year after year. Keep leaves and debris OUT so you spend more time enjoying your pool, not cleaning it. 【Solar Heating & Water Conservation】This 21ft pool cover for above ground pools utilizes solar energy to heat and maintain optimal pool water temperature while preventing up to 90% water evaporation—effectively conserving water. It helps stabilize water levels and shields your pool from sun damage. Spend less time refilling and enjoy a worry-free winter. 【Safe & Eco-Friendly Material】Certified by Amazon's "Climate Pledge Friendly" program, our pool cover is crafted from odor-free, eco-conscious transparent PU material. Safe even in high-heat environments—it won't melt or leave black residue—and far more environmentally responsible than silver-coated alternatives. Designed for pools and other round outdoor furniture, this comprehensive solution lets your family enjoy winters with complete peace of mind, season after season. Safety Warning Drowning hazard when used with pools. Keep children and pets away from the pool when the cover is in use. Always follow proper installation, use, maintenance, and storage instructions to minimize risks.
