We designed it with an eye for function, aesthetics, and simplicity (it’s about as complicated as a door hinge) so it offers up a secure belay and lower on a wide range of single ropes. On smaller diameter ropes, or when holding falls that generate extremely high loads (in excess of factor 1) the Cinch acts dynamically, reducing shock loads to the belay system. In addition, it will release easily and modulate fluidly while you’re rappelling or lowering off. The Cinch feeds rope easier than any other device, fits nicely in your hand, and weighs 182gm. For use on CE/UIAA dynamic climbing ropes only.
