This Petzl invention has revolutionized techniques for descending and belaying
in rock-climbing. As big a safety improvement as the seat belt is in motoring, it allows a climber to be belayed and lowered off. When necessary, the
GriGri also allows you to lock off the rope. The design of the GriGri limits its
use to indoor climbing or well equipped sport routes. It is used with a single
dynamic UIAA 10-11mm rope (9.7mm permitted). Individually tested.
Weight: 225 g.
CENote: The GriGri, in spite of its important contribution to security,
does not free the belayer from his or her responsibility to watch the
leader. As for any belay device or descender, training is essential
before use. When a fall occurs, the pulley turns on its axis and
squeezes the rope, causing a braking effect. It is, however, essential to
retain a light grip on the free end of the rope. The handle is used to un-jam the rope for
lowering the climber.
Attention: any time you unlock the device, you must keep a firm hold
on the free rope.
