5 ft - 8 ft Dock Buddy Stretch Dock Line

This product is a section of loosely woven hollow braid polypropylene covering a bungee cord which is secured between the two black sections. The polypro has a spliced eye at each end. The loose weave of the polypropylene cover expands when the Dock Buddy is short, but tightens and narrows as it is stretched (similar to the "Chinese Finger Cuffs" you played with as a kid). The internal bungee cord provides stretch, while the polypro cover ultimately limits how far the bungee can stretch. At ultimate stretch, most of the load is on the polypropylene cover.
