The 1' x 8' Single Water Tube is an effective and practical solution for securing your pool cover during the winter months. Designed for both above-ground and inground pools, this durable vinyl tube can be easily filled with water to keep the cover in place, preventing it from shifting, blowing away, or sagging under heavy snow and ice.

This water tube provides a simple, cost-effective way to ensure your pool remains well-protected during the off-season so that it’s ready for use when warmer weather returns.
