How it works
The running loop.
The everyday RunLock lock. The rope runs through one of its own loops, so the noose tightens under load and opens again when you slack it off. Over a tow hitch, a post, a bundle of firewood or a piece of game.
Step by step
4 steps. No knot.
The animation plays one step at a time and pauses. Click a step to jump to it, drag the slider to go back and forth, or play the whole sequence.
