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

Blue Wave Silver 12-Year Oval Above Ground Pool Winter Cover is a high-performance pool cover engineered to deliver long-lasting protection through the harshest winters. Specifically designed for oval above ground pool cover applications, this pool winter cover is constructed from premium polyethylene with a durable 10x10 scrim weave for enhanced strength. It includes a generous 4-ft overlap to ensure a tight, secure fit that won't slip under the stress of wind or snow. The black underside effectively blocks sunlight to slow algae growth, maintaining a clearer pool through winter. Precision heat-sealed seams reinforce the swimming pool cover, creating a barrier that resists splitting, leaking, or fraying over time. Metal grommets are spaced every 2 feet for balanced tension, allowing secure attachment using the included vinyl-coated cable and metal winch. This fastening system helps the above ground pool cover stay in place during extreme weather, while the added strength of the materials ensures multi-season reliability. The pool cover is designed in a forest green top with a black underside for aesthetic appeal and functional benefit. This oval pool cover is backed by a 12-year warranty. Offered in seven sizes—12-ft x 20-ft, 12-ft x 24-ft, 15-ft x 30-ft, 16-ft x 25-ft, 16-ft x 32-ft, 18-ft x 34-ft, and 21-ft x 41-ft—each cover is tailored for an exacting fit across a wide range of pool models.
