Made of durable, high quality, textured, flat cord that threads through each end, thebungee adjusts from 38" to 9". Once you've adjusted it to the right length for your job, it secures in place with a quick wrap-and-lock motion. Nite Ize even added small self-clipping plastic caps to the cord ends to keep them in place. No more pulling, stretching, and re-hooking to get the tension you want - job after individual job, the KnotBone Flat Bungee stays right where you attach it, pulls securely to the exact length you need, and locks there.
