The bottom line: this cover is best for people who need a solid, non-permeable winter barrier with extra overlap to simplify installation and withstand snow and ice. The included winch and cable and the four-foot overlap make setup straightforward, while the 12 x 12 scrim and 3.7 oz\/yd2 material aim to deliver long lasting protection through the season.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtra overlap:\u003c\/strong\u003e Four-foot overlap beyond the pool size makes installation easier and helps the cover sit loosely on the water without excessive stress.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolid waterproof design:\u003c\/strong\u003e The cover is a solid winter cover that will not allow water to pass through its material, keeping debris and precipitation off the pool.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable construction:\u003c\/strong\u003e Made from extra strength polyethylene at 3.7 oz\/yd2 with a 12 x 12 scrim, the material is designed for improved durability and resistance to tearing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded winch and cable:\u003c\/strong\u003e A winch and cable arrive with the cover for securing through grommets and optimizing performance in higher wind areas.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUV protection:\u003c\/strong\u003e The sandstone topside is coated to help prevent UV damage and extend the cover's useful life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacked warranty:\u003c\/strong\u003e A 15-year warranty provides long-term assurance on manufacturing and material performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Pool Mate 21 ft Extra Strength cover is aimed at above ground pool owners with a roughly 21 ft round pool who want a heavy-duty winter solution that is easy to install.
