Secure your pool cover with this set of 7.7FT pool tubes, featuring wind-resistant anchoring, knob-sealed leak-proof design, dual-chamber construction, and a durable blue finish—perfect for round, oval, and rectangular pools. Wind-resistant anchoring and anti-slip design—filled with water and placed along pool cover edges, uses weight to firmly secure cover, prevents wind lifting and slipping, keeps cover flat and taut. Knob-sealed and leak-proof with knob-style air valve—superior sealing performance prevents slow leaks, single filling maintains stable weighted state for extended periods. Wide-seam heat-sealing for double strength—widened heat-sealing process enhances sealing and durability, reduces leak risk, maintains performance in low-temperature or high-pressure environments. Dual-chamber design—significantly reduces rolling tendency, ensures greater stability, one chamber continues functioning if the other is damaged, providing redundancy and peace of mind for winter protection. Thickened PVC and flexible fit with 0.04mm thick high-quality PVC—resists low-temperature brittleness and UV aging, flexibly bends to fit edges of round, oval, and rectangular pools. Color: Blue.
