Constructed from thick woven polyethylene with heat-sealed seams and a coated sandstone topside, the cover includes a four-foot overlap and an installed winch and cable for perimeter fastening.

The Pool Mate 21 ft Extra Strength Platinum cover is aimed at owners of traditional above-ground pools who want a heavy-duty, weather-resistant winter solution. It’s ideal if you need a solid, non-draining cover with extra overlap for easier installation, robust material to resist winter wear, and a trusted warranty. If you have a very tall top rail or a nontraditional pool shape, measure carefully and consider sizing up or consulting Pool Mate for fit recommendations.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is this cover waterproof?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
