With carabiner clips instead of open hooks at each end, the KnotBone Bungee not only attaches to your anchor points, it locks there. Instead of elastic that loses its stretch over time, the KnotBone Bungee has a durable, high quality cord that threads through each end. Once you have it adjusted to the right length, secure it in place with a simple wrap-and-lock motion. Small self-clipping plastic caps at the cord ends keep them in place once youve got your load secured.
