Pool Mate 10 ft. Black Double-Chamber Extra Heavy-Duty Water Tubes for Winter Swimming Pool Covers 10-Pack

Double-Chamber Extra Heavy-Duty Water Tubes should be placed around the perimeter of your in-ground winter swimming pool cover. Simply slide these winter water tubes through the water tube loops included on your winter pool cover. These water tubes include leak-proof valves that are easy to fill with a garden hose. Only fill the water tubes half-way, this prevents ice from expanding and splitting your water bag. Made with Extra heavy-duty 20-Gauge vinyl. Color: Black.
