Blue Wave’s 15-year Solid Above-Ground Winter Cover is crafted from durable polyethylene with a 14x14 scrim count. This cover effectively protects your pool from winter elements by preventing water penetration. Reinforced heat-sealed seams add extra strength while the black underside helps ensure a clean pool in the spring. It features a generous 4-foot overlap for a proper fit. Each cover includes a metal winch and a heavy-duty vinyl-coated cable for securing the cover through the metal grommets spaced every 2 feet. Backed by a 15-year warranty with full coverage for the first 3 years.
