Assisted braking belay device from Petzl, the Grigri 2 is for ropes with a diameter of 8.9mm to 11 mm.
The Grigri's self-braking function helps the belayer catch and hold a climber, making it great for working routes, while it is equally good for lead climbing and top roping. Ergonomic design makes for smooth, controllable lowers.
The Petzl Grigri is also great for rappelling on single ropes - perfect for setting and cleaning routes.
The self-braking system works if the rope suddenly comes under tension in a fall, when the cam pivots to pinch the rope, thus helping the belayer stop the climber's fall. Usage is similar to that of conventional belay devices, where giving and taking slack is done by using both hands to slide the rope through the device, and falls are held by holding the free end of the rope.
For lowering and rappelling, the rate of descent is controlled by the hand holding the free end of the rope, when the rope is released with the handle.

Petzl: How It All Began
Fernand Petzl made the first 1,000 metre cave descent in France in 1950, laying the foundations for vertical safety technology of the future.
Twenty years earlier he had started working with fellow speleologist Pierre Chevalier, making new advances into the basic thinking behind their shared sport.
Fast forward to 1975, and the Petzl corporation was born at the base of the Dent de Crolles – Crolles’ Teeth – near Grenoble, heralding an era of innovation and design which brought us the Grigri belay device, Tikka and Tikkina head torches, and a range of safety helmets and harnesses used by cavers and climbers all over the world.
Renowned throughout the industry for their ‘work-at-height’ products and highly-technical rescue equipment, Petzl have expanded their manufacturing line to include specialist ice climbing technology, and are committed to raising social, environmental and ecological awareness - alongside research into risk prevention - of all mountaineering sports.
