Working principle

The GRIGRI + has an anti-panic handle that is especially useful in learning how to control a lower.

If the belayer pulls too hard on the handle, the anti-panic mechanism triggers and stops the descent.

To continue the descent, the belayer releases the handle completely, then resumes lowering normally.



As with all belaying maneuvers, the belayer must always hold the brake side of the rope.

Inconvenient triggering of the anti-panic handle

In certain cases, the anti-panic mechanism can trigger inconveniently (if there is rope drag, with a lightweight climber, on reaching the ground...).

To unblock the rope and complete the lower, you can pull the handle completely back. This overriding of the anti-panic function is for exceptional use only.

Particular case:

Warning: in certain configurations (lightweight climber and/or belayer, rope drag, small diameter rope, new rope...), the triggering of the anti-panic handle may be too subtle for the belayer to notice. Even with the anti-panic handle, you must always hold the brake side of the rope to stop the descent.

Remember: novice belayers are advised to avoid using a rope that is too thin.
