Swimline 1 x 10 Foot Winterizing Closing Double Water Tube Weight for Inground Swimming Pool Covers

The Swimline 10-Foot Double Water Tube is made specifically for use with your rectangular or oval pool cover to eliminate stress on your pool and the cover. It's 33% heavier than other water bags, making it super durable - plus its valves are easy to fill up with a garden hose. This Swimline water tube is best used with in-ground pool covers. Covering your pool with a winter cover keeps out dirt and debris, and this water tube helps keep the cover in place. We are an Authorized Swimline Swimming Pool parts dealer!
