Key Features:

• Boost Winter Pool Security: This 4-pack of 2 x 1.85 ft corner winter water bags for pool is designed to securely anchor your winter pool cover in place. Once filled, they add reliable weight to prevent wind lift and keep debris out. Ideal for inground pools, they're easy to fill, drain, and store—keeping your pool protected all winter and saving cleanup time.
• Thickened PVC Construction: Made from 0.4 mm thick flexible PVC, these pool cover water bags resist impact, UV damage, and minor bumps. Once filled, they provide a stable counterweight to keep your cover from lifting. Fill 50–70% capacity to allow for expansion and avoid ruptures caused by freezing or thermal changes—ideal for year-round use.
• Durable Welded Edges: Crafted using high-frequency heat sealing with a 0.59-inch seam width, the edges are tough, leak-resistant, and crack-proof. These pool cover water tubes stay reliable in extreme weather—from scorching summers to icy winters—ensuring long-term durability season after season.
• Twist-Seal Leakproof Cap: Designed for ease, the twist-on cap features a built-in rubber gasket for a tight, leakproof seal. The anti-loss design keeps the cap attached, while the threaded closure offers better sealing than standard snap caps. Tip: Slide the retaining ring to the base of the twist pattern before filling for optimal sealing.
• Efficient Single-Chamber Design: The pool cover weights feature streamlined single-chamber structure speeds up filling and simplifies placement. Whether you're working alone or with help, setup is quick and easy. Ideal for routine pool cover anchoring and winter maintenance.
