The ROCKER has a split personality... One moment it is a dynamic grab and and the next an ascender. This dual action device has a place on your rack and sports an internal camming mechanism that allows the rope to dynamically slip when loads exceed 3 - 4 kN... a great safey factor that not only protects you but also your rope from damage. Rocker can be used as a belay device, wall hauling cam, an ascender, self belay for short fixing and also solo aid device. A great versatile addition to your rack.
