Designed to help absorb shock to boats, cleats, docks, pylons, and other hardware, a bungee cord is hidden inside the rope and acts as a built-in snubber. The 2 foam floats protect the boat from chafing, and there is a sliding adjustment at both ends for quick docking. This line is recommended for docking boats and PWCs up to 3,500 lbs. (1,887.6kg). Bungee Dock Lines have a tensile strength of 2,150 lbs. (975.2kg). The Bungee Dock Lines is 6' (1.83m) and stretches to 9' (2.74m).
