Belay device with assisted braking
1. Field of application
Belay device for 10 to 11 mm (9.7 mm is acceptable) CE (EN 892)
and/or UIAA certified dynamic single ropes (core + sheath).
The GRIGRI is designed for indoor wall climbing or for rock climbing
on well-protected routes where anchors meet the EN/UIAA standard
(25 kN). It can be used to belay and lower a leader or a second.
It should not be used for mountaineering or adventure climbing.
Before using the GRIGRI, you must know the proper belaying
techniques.
The GRIGRI's assisted braking capability does not remove
the need for you to adhere to basic belaying principles: be
vigilant, attentive, always hold the braking side of the
rope, etc.
The new belaying technique (developed by climbers) is more
ergonomic; nevertheless, the old technique may still be used - see
www.petzl.com

3. Inspection, points to verify
Before each use:
Verify that the product has no cracks, deformation, marks, excessive
wear, corrosion, etc.
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 there are no foreign objects (sand, etc.) in the mechanism and
no lubricant in the rope path.
Consult the details of the inspection procedure to be carried out for
each item of PPE on the Web at www.petzl.com/ppe or on the PETZL
PPE CD-ROM.
Contact PETZL if there is any doubt about the condition of this
product.
During each 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 pieces of equipment in the system are correctly positioned with
respect to each other.
Verify that the carabiner is always loaded on its major axis. Verify
that it is locked.
WARNING: Be careful of foreign bodies which can impede the
operation of the cam.
4. Compatibility
Verify that this product is compatible with the other elements of the
system in your application (compatible = good functional interaction).
Ropes
Compatible with 10 to 11 mm (9.7 mm is acceptable) CE (EN 892)
and/or UIAA certified dynamic single ropes (core + sheath).
WARNING, certain ropes can be slippery and thus reduce the
GRIGRI's braking effectiveness, for example new ropes, certain
sheath constructions and/or sheath treatments, wet ropes, etc. (see
the instructions specific to the rope).

Attachment carabiner
You must use a locking carabiner that meets current standards.
5. Working principle
In a fall, the GRIGRI pivots on the carabiner, the rope becomes taut
and the cam pinches the rope, applying a braking force to it. The
brake hand (holding the braking side of the rope) helps engage the
cam, so you must always hold the braking side of the rope. The use
of gloves is recommended.
The GRIGRI must be able to function freely at all times. The GRIGRI
and its cam must be allowed to rotate freely.
WARNING: any blockage or constraint of the device, or of the
cam, negates the braking action on the rope: DANGER OF
DEATH.
6. Setting up and installation of the
descender
Insert the rope as indicated by the drawings engraved on the side
plates and on the cam.
Close the GRIGRI's moving side plate and clip a locking carabiner
through the two attachment holes. Attach the GRIGRI to the belay
loop of your harness, following the instructions for use of the
harness, and lock the carabiner.
7. Function test
A test must always be done before each use to ensure correct rope
installation and to verify that the GRIGRI is functioning properly.
Give a sharp tug on the climber's side of the rope while holding the
braking side of the rope. The rope must jam in the GRIGRI. Once the
tension is released, the rope must slide normally.
WARNING, if the rope does not jam in the GRIGRI, there is a
danger of death for the climber.
Verify that the rope is correctly installed.
8. Belaying the leader
When you belay with the GRIGRI, keep in mind two important
principles:
- Always hold the braking side of the rope.
- Do not grip the device with your entire hand.
8A. Paying out slack
Get into the habit of keeping your hands on the rope in this
«principal» belaying position (see drawing).
The belayer holds the braking side of the rope with one hand, and
holds the climber's side of the rope with the other hand.
To facilitate feeding the rope, focus more on pushing the rope into
the device rather than pulling it out (rotary movement).
This position allows you to:
- Give or take in slack.
- Arrest a fall (see chapter 8D).
Your hands should always stay in this position, except if you need to
give slack quickly when the leader is clipping.
Always hold the braking side of the rope.
8B. Giving slack quickly when the leader is
clipping.
At certain times, when the leader needs slack quickly for clipping,
the belayer can have difficulty giving slack quickly to the climber. To
overcome this difficulty, brace the index finger of your brake hand
(still holding the braking side of the rope) against the lip on the
moving sideplate and press your thumb on the cam.
The other hand holds the climber's side of the rope.
Your hands must immediately return to the principal belaying
position.
ATTENTION, this procedure must only be used on a limited
basis and must be executed very quickly.
In case of a fall, you risk clenching the GRIGRI's cam, which would
negate the braking of the rope.
Always hold the braking side of the rope.
Do not keep the thumb continuously pressed on the cam.
8C. Taking up slack
Once the leader has clipped, you must return immediately to the
«principal» belaying position to take up slack.
Take up slack until the leader reaches the quickdraw. Then begin
giving slack again.
Always hold the braking side of the rope.
8D. Arresting a fall
To effectively arrest a fall, firmly grip the braking side of the rope
while pulling downward on it.
Tip: Make a small jump to soften the impact of a leader fall.
Always hold the braking side of the rope.
9. Belaying a second in a top-rope
situation
Regularly take up slack in the rope. Use both hands to slide the rope
through the GRIGRI. Never let go of the braking side of the rope. To
arrest a fall, see chapter 8D.
Always hold the braking side of the rope.
10. Lowering a climber in a toprope
situation
The belayer takes up all slack in the rope and then puts his body
weight on the rope. The belayer firmly grips the braking side of the
rope.
The climber, hanging on the rope, is ready to descend.
The belayer gradually pulls on the release handle without letting go of
the braking side of the rope. The handle can assist in braking, but the
rate of descent is controlled by varying the grip of the brake hand on
the braking side of the rope.
Do not forget to tie a knot in the bottom end of the rope.
Always hold the braking side of the rope.
