Corner Pool Water Tubes, 4 Pack 22.4 x 22.2 in, Corner Winter Water Bags with Leakproof Screw Cap, 0.4mm Heavy Duty PVC, Cold-Resistant Weights for Inground Swimming Pool Covers

4 Pack Corner Pool Cover Water Bags

Each 22.64 x 22.24 inch corner pool cover water bag is specially designed for harsh winter weather. Perfect for securing the corners of your pool cover, it helps block leaves and debris from entering the pool—keeping it cleaner and reducing maintenance all season long.

Crafted with upgraded thick PVC, these pool cover water bags resist tearing and punctures even with repeated use. When filled, they provide reliable weight and stand up to the elements—ideal for long-term outdoor application.

Features an integrated twist-seal valve with a wide opening, the pool cover water tube fits most garden hoses for quick and hassle-free filling. High-frequency welded 0.59" seams ensure superior leak resistance. The single-chamber design speeds up filling and makes setup easy.

This set includes four corner water bags for pool cover, specially designed to anchor pool cover corners—often left exposed by standard water tubes. They enhance edge sealing and wind resistance, keeping the entire cover firmly in place.

Built for year-round use, the material resists UV damage in the heat and remains flexible in cold weather. No cracking, no hardening—just reliable protection season after season.
