Product Information

Specification

Boost Winter Pool Security :

This 4-pack of 2 × 1.85 ft corner winter water bags is designed to securely anchor your pool cover throughout the winter season. Once filled, they provide reliable weight to prevent wind lift and block debris. Ideal for inground pools, these bags are easy to fill, drain, and store—keeping your pool protected all winter and reducing cleanup time.

Thickened PVC Construction :

Built with 0.4 mm flexible PVC, these corner water bags withstand UV exposure, impacts, and minor abrasions. When filled, they offer stable counterweight support to keep your pool cover firmly in place. For best results, fill them to 50–70% capacity to allow for expansion during freezing or temperature changes.

Durable Welded Edges :

Reinforced with high-frequency heat-sealed seams and a 0.59-inch edge width, these bags are leak-resistant and crack-proof. They maintain reliable performance through extreme weather—from hot summers to freezing winters—ensuring long-lasting durability year after year.

Twist-Seal Leak-Proof Cap :

The twist-on cap features a built-in rubber gasket for a secure, leak-proof seal. The anti-loss design keeps the cap attached, while the threaded closure provides better sealing than traditional snap caps. Tip: Slide the retaining ring to the bottom of the thread before filling for the best seal.

Efficient Single-Chamber Design :

The streamlined single-chamber construction speeds up filling and makes placement easier. Whether installing alone or with assistance, setup is quick and hassle-free. Perfect for everyday pool cover anchoring and winter maintenance.
