8-ft. Double Water Tubes Weights for IG Pool Covers (Blue) - 6 Pack
Heavy-duty durable vinyl water tubes that won't break or split! Double chamber water tubes are better able to stay securely in place and won't roll like single-chamber alternatives. An added benefit is that if one side becomes punctured, there is still enough weight from the other chamber to hold your cover down -- no rush to replace a water tube in cold weather. These vinyl bags are up to 35% heavier than other versions on the market and yield significantly more strength and puncture-resistance. Our double chamber water tubes feature no-leak valves and are easy to fill using a standard garden hose.
