Add a little extra zing and excitement to your tubing! This 9/16” x 50 ft. tube rope has a 3/8” diameter bungee cord spliced inside. It’s rated at 4,150 pounds tensile strength, conforming to WSIA recommendations for 1 - 4 rider tubes. You’ll enjoy brief surges of speed as the bungee stretches and contracts. It reduces wear and tear on tubes and riders too, by absorbing sudden jerks from slack in the line. A Rope Keeper is included for convenient storage.
