Add a little extra zing and excitement to your tubing with the Bungee Tow Rope Extension. This 9/16" x 3' polypropylene tube rope has a bungee cord spliced inside, so riders 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. The Tow Rope Extension has a tensile strength of 4,150 lbs. Stretches to 5' long.
