Inspection, points to verify
Petzl recommends a detailed inspection at least once every 12 months. Warning: your intensity of use may cause you to inspect your PPE more frequently. Record the results on your PPE inspection form: see examples at Petzl.com.
Before each use
Verify that the product has no cracks, deformation, marks, corrosion… Check
the state of wear.
Verify that the cam and release handle move freely and that the springs are
working properly.
Check the condition of the cam and the friction plate.
Verify that there are no foreign objects (sand…) in the mechanism and no
lubricant on the rope path.
During use
It is important to regularly monitor the condition of the product and its
connections to the other equipment in the system. Make sure that all items of
equipment are correctly positioned with respect to each other.
Verify that the carabiner is always loaded on the major axis, closed, locked.
Verify that the cam and the frame of the GRIGRI + are able to rotate freely at
all times.
Compatibility
Verify that this product is compatible with the other elements of the system
in your application (compatible = good functional interaction). Ropes
Compatible with 8.5 to 11 mm CE EN 892 and/or UIAA certified dynamic
mantelshelf single ropes.
Warning: commercially, nominal rope diameters have a tolerance of up to
±0.2 mm.
Warning: the blocking effectiveness of the GRIGRI + may be reduced when
used with a new rope. In general, blocking effectiveness and ease of giving
slack can vary depending on the diameter, condition, state of wear, and
surface treatment of your rope. Be vigilant and familiarize yourself with the
belaying and lowering performance of your GRIGRI + each time you use a rope
other than the one you normally use.
WARNING: certain ropes can be slippery and reduce the blocking
effectiveness of the GRIGRI + (ropes with sheath treatments, ropes that are
new, icy, wet, muddy…). Choose the rope diameter based on the intended use.
Our recommendations regarding rope diameters are as follows:
8.9 ≤ Ø ≤ 10.5 mm:
The device functions optimally with these rope diameters.
10.5 < Ø ≤ 11 mm:
For well-used or large-diameter ropes, you may need to use the technique presented in section 8C more frequently to facilitate giving slack.
8.5 ≤ Ø < 8.9 mm:
Thin ropes require special precautions during use because they are more difficult for the hand to grip. They can be more difficult to control while descending or in the event of a fall. The use of thin ropes requires greater vigilance and a high level of experience with belay techniques.
Attachment carbine
You must use a locking carbine that meets current standards in your country.
Function principle and test
When a climber falls, the GRIGRI + pivots on the carbine, the rope becomes
taut and the cam pinches the rope to block it. Holding the brake side of the
rope helps engage the cam, so it is important to always hold the brake side of
the rope.
The cam (a) and the frame of the GRIGRI + (b) must be able to rotate
freely at all times. The GRIGRI + must be free to rotate around the carbine.
WARNING: any blockage of the device or cam will negate the blocking
action on the rope.
GRIGRI + installation
A test must be carried out before each use to ensure correct rope installation and to verify that the GRIGRI + is functioning properly.

Choosing the belay mode
You can use the selector knob to choose the belay mode (top-rope or lead
climbing).
The top-rope belay mode facilitates taking up slack, but does not allow giving
slack using the technique shown in section 8B.
Locking the knob:
The selection can be locked by using the lock button.
Belaying techniques
Before using the GRIGRI +, you must know the proper belaying techniques. The GRIGRI +’s cam-assisted blocking capability does not relieve you of the need to follow basic belaying principles: be attentive to the climber’s progress and always hold the brake side of the rope.
8A. Primary belaying position
When you belay with the GRIGRI +, keep in mind some important principles:
- Always hold the brake side of the rope.
- Never grip the device with your entire hand.
- Anticipate clips by being attentive to the climber’s progress.
Your hands should always stay in this position, except if you need to give slack quickly when the climber is clipping (see section 8C).
8B. Giving slack
To facilitate feeding the rope, focus more on pushing the rope into the device
than pulling it out (rotational movement).
8C. Giving slack quickly
One technique is to simply move toward the cliff.
The other technique, for occasional and short-term use, requires different
hand positioning for a very limited time.
Your hands must immediately return to the principal belaying position.
Warning: in the event of a fall, you risk clenching the cam, which
negates the blocking action on the rope.
Do not keep your thumb continuously pressed on the cam.
8D. Taking up slack
8E. Stopping a fall
Tip for a dynamic belay: do a small jump, or step forward, to reduce the
impact force on the climber.
Lowering a climber on a top rope
The be layer gradually pulls on the release handle, without letting go of the brake side of the rope. The handle helps adjust the friction, but the descent is controlled by the hand gripping the brake side of the rope.
Triggering the anti-panic mechanism
Working principle
The GRIGRI + has an anti-panic handle that is especially useful in learning
how to control a lower.
If the be layer pulls too hard on the handle, the anti-panic mechanism
triggers to help stop the running of the rope. By holding the brake side of
the rope, the brake hand helps engage the cam to stop the descent. To continue
the descent, release the handle completely, then resume lowering normally.
Exceptional use
In certain cases (e.g. when reaching the ground, if there is rope drag, or
with a lightweight climber), unintentional triggering of the anti-panic
mechanism can occur. To facilitate completing the lower, you can pull the
handle completely back. This technique is for exceptional use only.
Warning
In certain configurations (lightweight climber and/or be layer, rope drag,
small-diameter rope, new rope…), the triggering of the anti-panic mechanism
may be too brief to be noticed by the be layer. Even with the anti-panic
handle, you must always hold the brake side of the rope.
