Knot Bone Cord Lock #3
Unlike spring-activated cord locks, the NiteIze KnotBone Cord Lock has no moving parts that can slip, jam with snow or ice, break, or rust. The simple design of this Cord Lock from NiteIze allows you to secure the ends of pull cords of all kinds to the exact tension you need, and keeps them from getting absolutely locked in place until you release it. To use, simply thread both ends of your cord through the Cord Lock's closed end, pull to the desired tension, wrap and lock. (For a loose cinch, just slide the KnotBone Cord Lock to the position you want without wrapping - it holds a natural grip on the cord).
