21 FT Round Winter Pool Cover for Above Ground Pools, Cable and Pulley

Features

• Rope Adjusts, Cable Holds: The nylon rope moves smoothly through the pulley for easier positioning and adjustment, while the low-stretch steel cable helps maintain firmer perimeter tension. Because nylon rope may gradually stretch under continuous pressure, the added cable helps reduce loosening and provides a more stable connection during extended winter coverage.
• Cold-Resistant Woven PE Tarp: Designed as a winter pool cover for seasonal outdoor use, the woven PE tarpaulin helps shield the pool from snow, rain, leaves, dust, and debris in temperatures down to -10F (-25C).
• Wind, UV and Tear Resistance: The UV-resistant, tear-resistant woven tarp helps withstand prolonged sun exposure and everyday wear, while the rope-and-cable closure helps reduce wind lift around the pool edge during changing fall and winter weather.
• Easy One-Person Pulley Tightening: Center the cover, connect the nylon rope and steel cable as directed, then pull through the pulley to adjust the fit. The pulley-assisted design makes installation and tightening easier with less effort, allowing one person to set the perimeter tension without complicated tools or difficult knots.
• 3 FT Overlap for Round Above-Ground Pools: Each cover includes a 3 FT overlap for easier centering, positioning, and fastening. Designed for round metal-frame and hard-sided above-ground pools; select the size that matches the full outside pool diameter, including the top rail.
