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.

Notes

Note:

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.
