The cover is a solid design that does not allow water to pass through its material, and it arrives with a winch and cable for perimeter fastening. A four-foot overlap is built into the sizing to make installation easier and give you room to secure the cover properly.\u003c\/p\u003e\n\n\u003ch3\u003eHow strong is the material and what does that mean for durability?\u003c\/h3\u003e\n\u003cp\u003eThe Robelle Supreme uses a tightly woven 12 x 12 scrim and heavyweight polyethylene fabric. Higher scrim counts and material weight are reliable indicators of tear resistance and resistance to winter wear, so this cover is engineered to resist punctures and stretch.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e12 x 12 scrim weave for superior tensile strength\u003c\/li\u003e\n  \u003cli\u003eExtra heavy-duty polyethylene at industry-leading weight for long life\u003c\/li\u003e\n  \u003cli\u003eConstructed approximately 85% heavier than common standard covers\u003c\/li\u003e\n  \u003cli\u003eBacked by a 15-year warranty for added reassurance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I install and secure the cover for the winter?\u003c\/h3\u003e\n\u003cp\u003eThe cover includes a winch and cable so you can thread the cable through the grommets and snug the cover perimeter.

The Robelle 21 ft Professional Supreme Winter Pool Cover is aimed at above-ground pool owners who want a long-lasting, heavy-duty seasonal cover that resists tears, keeps water out, and simplifies winter pool closing. It’s a strong choice for homeowners in colder climates or high-wind areas who value a solid cover with professional-grade materials, a generous overlap for easier installation, and an included winch-and-cable fastening system. For additional anchoring or deck installations, add cover clips, cover wrap, or vinyl water weights as needed.\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: Does the Robelle 21 ft cover allow water through the material?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. This is a solid winter cover that does not let water pass through the polyethylene material.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is the winch and cable included and how is the cover secured?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
