4-Pack Heavy Duty Winter Pool Cover Water Bags - 26 Gauge PVC Corner Anchors for Inground Pools

Features

• Constructed from high-quality, flexible 0.4mm (26 gauge) PVC material, these water bags offer exceptional resistance to impact, UV rays, and minor abrasions. This robust build ensures they remain intact through scorching summers and icy winters, providing a long-lasting solution for your pool maintenance needs.
• Say goodbye to messy leaks with our advanced twist-on cap featuring a built-in rubber gasket. The anti-loss design keeps the cap attached, while the threaded closure creates a superior seal compared to standard snap caps, ensuring your anchor weight stays consistent all season long.
• Crafted using high-frequency heat sealing with a generous 0.59-inch seam width, the edges of these pool cover weights are tough and crack-proof. This reinforced construction prevents splitting under pressure, making them reliable anchors even in extreme weather conditions.
• Designed specifically to anchor winter pool covers, this 4-pack adds reliable counterweight to the corners of your inground pool. By preventing wind lift, they keep leaves and debris out of the water, significantly reducing your spring cleaning workload and protecting your pool liner.
• These water tubes are intelligently designed to handle thermal changes. We recommend filling them to 50–70% capacity to allow for water expansion during freezing temperatures, preventing ruptures and ensuring your pool cover stays securely in place year after year.
