Lead Belay with the Gri-Gri

Belaying a leader in a climbing gym with a Gri-Gri requires some skills you won't have learned if you've only belayed with ATC-type devices. Luckily it's not hard to make the adjustment.

For an overview, check the Petzl technical page: Belaying with the GRIGRI 

The big thing to learn is how to momentarily allow rope to be pulled through the GRIGRI without blocking the cam's action.

  1. Hold the rope with at least three fingers.
  2. Use the index finger to support the GRIGRI
  3. The thumb presses on the cam.

The action must be momentary, and as soon as the leader has clipped return to the primary belaying position.
