Winter Block Premium Water Tubes for Winter Pool Cover, Double Chamber Tubes for Inground Pool, Heavy Duty Water Bag Weights for Winter Pool Cover, 8 ft. (6 Pack)

Our Winter Block double chamber pool tubes are a must have during pool closing season. They will keep your inground pool winter cover locked into place during harsh winter conditions. Crafted from a heavy-duty puncture resistant vinyl, they feature a leak-proof valve that is easy to fill with a garden hose. We recommended filling the bag 1/2 to 3/4 of its full capacity to prevent popping caused by expansion if the water freezes. To install the bag simply place the bag on your inground pool winter cover into the correct position and fill with water.
