Blue Wave Silver 12-Year 21-ft x 41-ft Oval Above Ground Pool Winter Cover

Closing a pool for winter should not mean months of cleanup or a green pool in spring. The Blue Wave Arctic Armor 21-ft x 41-ft Oval Above Ground Pool Winter Cover is a heavy-duty solid pool tarp built to handle everything the off-season brings, so you can close up in fall and return to a cleaner pool when spring arrives. It’s made with a 10x12 scrim woven polyethylene, a dense, tear-resistant material that forms a solid barrier against leaves, sticks, rain, and snow. The reinforced, heat-sealed seams form a watertight bond across the cover to block moisture and debris and help prevent rips. Because the panel is solid rather than mesh, it keeps water from passing through and limits evaporation over winter. The black underside blocks sunlight throughout the off-season to help limit dirt buildup in the pool, which reduces the maintenance work needed at opening time. Securing the cover is straightforward. The rust-resistant aluminum grommets spaced every 2 feet work with the included vinyl-coated cable and metal winch to lock the cover down evenly, withstanding strong winds, rain, and snow. The 4-ft overlap extends well beyond the pool wall for a snug, wind-resistant fit, and a helper makes installation faster on a pool this size. This is a winter debris cover, not a safety cover. Do not walk on it or allow it to support weight. After a heavy snow, clear the buildup from the pool edge with a soft-bristle broom. To keep the pool cleaner, use a cover pump to remove standing water that collects on top of the cover after storms. Backed by Blue Wave’s 12-year limited warranty (full coverage in year 1 and prorated coverage in years 2 through 12), U.S.-based customer support and over 35 years of pool industry experience. This swimming pool cover is sized for 21-ft x 41-ft oval pools only. Complete with securing hardware, including the winch and cable, so everything needed for installation is in the box.
