The GRIGRI is a belay device with assisted braking designed for belaying both in the gym and at the crag. Compact and lightweight, it can be used with single ropes from 8.5 to 11 mm. The assisted braking function makes belaying more convenient when holding a climber or catching a fall. The design of the handled camming mechanism enables exceptional descent control.
