Robelle 8-foot Double-chamber Winter Water Tubes for Swimming Pool Covers Black 16 Gauge 6 Pack

Robelle 8-foot double-chamber winter water tubes are used to hold down in-ground swimming pool covers during the winter. Deluxe tubes are constructed of heavy-duty 16 gauge puncture resistant vinyl. Premium tubes are constructed of extra heavy-duty 20 gauge puncture resistant vinyl. Customers prefer double-chamber tubes because the dual chamber design prevents rolling and provides insurance if one chamber leaks. Includes two conveniently placed and leak-proof valves that are easy to fill with a garden hose. Water tubes keep your pool cover in place all winter long. Place water tubes around the perimeter of your pool cover using the loops on your cover. Water tubes should be filled half-way to prevent popping caused by expansion if the water freezes.
