Add a little zing to your tubing. You'll enjoy surges of speed as this bungee rope stretches and contracts. This rope also reduces wear and tear on tubes and riders by absorbing sudden jerks from slack in the line. Includes rope keeper. 9/16" x 50' with 3/8" bungee cord spliced in. 4,150-lb. tensile strength. Note: Bungee end of the tow rope should always be attached to the boat – NEVER the tube.
