The Petzl GRIGRI is a belay device featuring assisted braking, an ergonomic handle, and the ability to have progressive control over the rope. It is primarily designed for belaying on the crag and in the gym.

 

An optimally balanced design means it is lightweight (175g) compact and durable. 

 

The assisted braking function improves comfort while belaying, holding a climber, or catching a fall. The design of the handled camming mechanism enables exceptional descent control.

 

Feeding slack and catching falls are accomplished using standard belay techniques, always keeping a hand on the brake side of the rope. 

 

Compatible with 8.5 to 11 mm dynamic single ropes and optimized for 8.9 to 10.5 mm. The 3:1 mechanical advantage of the handled camming mechanism helps control rope feed on small-diameter ropes and requires less effort on the handle for large-diameter ropes.
