8 ft. Black Single-Chamber Heavy-Duty Water Tubes for Winter Swimming Pool Covers (5-Pack)

Single-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 a leak-proof valve that is 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.
