Dynamic belaying with the GRIGRI

Some think that dynamic belaying with the GRIGRI is difficult. But it is the belayer, not the belay device, that plays the primary role in dynamic belaying.


  • 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.

The key to dynamic belaying: step or make a small jump forward when the climber falls. We also stress that dynamic belaying does not mean keeping 3-4 m of slack in the climber side of the rope: this does not reduce the force of a fall. In addition, in the case where the climber has not gained enough height, it increases the risk of a ground fall.

In any case, it is necessary to be attentive and vigilant while belaying, so that potential falls can be anticipated. Remember that where there is a risk of a ground fall, or striking a ledge, a dynamic belay should not be used.

It takes practice to master dynamic belaying. To practice, start with falls sufficiently high relative to the ground (for example, when the climber is nearing the end of a pitch).
