Petzl's GriGri belays more smoothly than previous models; it's smaller and lighter and designed to work with the thinner ropes popular today. The belay device can be used with ropes between 8.9 and 11 millimeters in diameter. Its "descent control system" provides a larger sweet spot when lowering a climber or rappelling. It weighs in at 170 grams, making it an easy choice when packing for even the longest hike-to climbs.
Belay technique identical to classic belay systems — both hands on the rope. A fall is stopped by tightening the hand on the free end of the rope.
Assisted braking capability: During fall arrest, the belayer holds the free end of the rope, the cam pivots and pinches the rope, increasing the braking action until the rope stops sliding.
Design allows excellent control during the descent. One hand holds the rope and the other uses the handle to unlock the cam. The handle design allows a very gradual release of the rope. In combination with the strong braking action of the cam, it gives a feeling of control when lowering a partner or rappelling.
Compact and ultra-light at 185 g (25% smaller and 20% lighter than the GriGri)
The construction includes a stainless steel friction plate and cam to ensure a long product life
For 8.9 to 11 mm single ropes (ideal at 9.4 to 10.3 mm)
