Pool Mate 10 ft. Black Double-Chamber Heavy-Duty Water Tubes for Winter Swimming Pool Covers 5-Pack

Double-Chamber 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 Heavy-Duty 16-Gauge vinyl. Color: Black.
