The Trango Cinch is the latest in a long line of innovative belay devices introduced by Trango. It has been designed with an eye for function, aesthetics and simplicity (It's about as complicated as a door hinge) so it offers up a bombproof belay for ropes from 9.4mm to 11mm. 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 170 grams.
