Belaying with the GRIGRI
The belay technique to be used is very similar to the generic belay technique, but has a few specifics. So it requires a little time to adapt to. The technique described here is the only one that Petzl recommends.
- Carefully read the Instructions for Use used in this technical advice before consulting the advice itself. You must have already read and understood the information in the Instructions for Use to be able to understand this supplementary information.
- Mastering these techniques requires specific training. Work with a professional to confirm your ability to perform these techniques safely and independently before attempting them unsupervised.
- We provide examples of techniques related to your activity. There may be others that we do not describe here.

- basic technique and giving slack
- the technique for quickly giving slack.
It is also important to stress the fact that any blocking of the device or the cam will negate the blocking action on the rope. This is why it is essential to avoid holding the device with your whole hand, to avoid keeping your thumb constantly on the cam, to avoid blocking the cam...
It is difficult to make an exhaustive list of all incorrect techniques. Here are some illustrations:
Holding the GRIGRI with the entire hand.
Giving slack without holding the brake side of the rope.
Incorrect placement of the index finger.
Holding the climber side of the rope.
Note that the use of incorrect belay technique is the primary risk factor in an accident, especially when the belayer is surprised by a fall. If you recognize yourself in any of these illustrations of incorrect technique, adopt the technique presented at the beginning of this paragraph.
