Reverso

A Reverso is a belay device developed and patented by Petzl, used for example in rock-climbing and other activities which involves rope-work. Another version of this device is the Reversino, intended for use with thinner ropes.

A Reverso can be used to belay the leader, one or two seconds, or a descender during rappelling. It can also be used in self-braking mode, to belay one or two seconds, if attached directly to the belay.
