Product Information

Specification

Complete Pool Cover Kit :

This set includes six 8 ft × 0.67 ft pool cover water bags and four 2 ft × 1.85 ft corner tubes, providing full-edge and corner anchoring for your pool cover. It improves wind resistance, blocks leaves and debris, and keeps your cover securely in place throughout harsh winter conditions—reducing cleanup time and effort.

Thickened PVC Material :

Constructed from 0.4 mm thick, flexible PVC, these inground pool cover water bags are built to withstand impact, sun exposure, and seasonal wear. Once filled, they deliver reliable weight to hold your cover firmly. For best results, fill each bag to 50–70% to allow room for expansion and prevent damage during temperature changes—ideal for year-round use.

Reinforced Welded Seams :

Featuring high-frequency heat-sealed edges with a 0.59-inch seam width, these water tubes offer outstanding leak resistance and durability. They are designed to endure strong sunlight and freezing weather without cracking, tearing, or aging.

Twist-Lock Leakproof Cap :

Each water bag is equipped with a twist-lock cap and built-in rubber gasket for a secure, leakproof seal. The tethered cap prevents misplacement and offers improved sealing compared to traditional snap caps. Tip: Slide the retaining ring to the base of the spiral before filling for the best seal.

Single-Chamber Convenience :

The simple single-chamber design ensures quick filling and easy placement. Whether you're setting up alone or with assistance, installation is fast and hassle-free. These water bags make stabilizing your winter pool cover easier and more efficient.
