GriGri 2 Descender by Petzl, 10-11mm

Self-Braking Belay Device. This unique belay device for ropes works much like an automobile’s seat belt.  When movements are slow, the rope runs freely through the device; when there is a shock load, it locks, jamming the rope with its internal cam device. This device can help eliminate some potential belaying errors, but not all of them. The Grigri is not a substitute for skilled, vigilant belaying. Works on 10mm to 11mm ropes.

As of Monday, June 20, 2011, Petzl has issued a RECALL FOR REPLACEMENT FOR ALL GRIGRI 2 assisted braking belay devices (D14 2O, D14 2G, D14 2B) from serial number 10326 through 11136, sold after January 1, 2011. Please stop using the device and contact Petzl directly using the link below for instructions on the recalled product:
