Nomenclature of parts
(1) moving side-piece, (2) cam,
(3) axle, (4) handle, (5) fi xed
side-piece: Principal materials:
aluminium alloy (side-pieces),
stainless steel (cam).
Inspection, points to verify
Check the following before each
use: the fi xed and moving side-
pieces, the friction components
(cam groove), the locking
components (axle), the operation
of the springs in the cam and
handle. Finish with an operational
check (see diagram 2). If there is
any doubt about the condition of
the device, return it to PETZL for
inspection.
Instructions for use
This product is a belay device for
the leader or second on a rope.
It has been developed for indoor
wall climbing or for climbing
on well-protected sport routes
where anchors meet the UIAA
standard. It should not be used
for mountaineering or adventure
climbing. It is designed to be used
with a UIAA dynamic single rope,
10-11 mm in diameter (9.7 mm
is acceptable). However, extreme
CAUTION should be exercised
if using a rope that is less than
10 mm in diameter because the
human hand cannot effectively
grip a thin rope, particularly while
rapelling or lowering. The use of
static or semi-static ropes is limited
to rappelling and top-roping. The
user must receive specifi c training
and always remain alert.
Diagram 1. Installation of the
rope
The rope must be inserted as
indicated by the diagrams engraved
on the device. The GRIGRI is then
closed and secured with a locking
carabiner.
Diagram 2. Test and
functioning
An operational check must always
be carried out before each use to
ensure correct rope installation
and to verify that the device is
functioning properly. The rope on
the climber's side should jam when
it is given a sharp tug or pull. The
tension on the rope makes the cam
pivot on its axis and clamp down
on the rope. When the tension
on the rope is released, the cam
returns to its initial position.

BE CAREFUL to avoid getting dirt
or sand in the device as well as
any lubricant on the surfaces
which come in direct contact with
the rope.
Diagram 3. Belaying the
Leader
It is essential for the belayer to
be securely anchored before
belaying a fellow climber. The
belayer attaches the device
directly to his/her harness with
a locking carabiner. Acting as a
counterweight, the belayer helps
absorb the shock from a fall by the
leader.
3A. Feeding out rope
The belayer holds the free end of
the rope with one hand and the
rope from the climber with the
other. To facilitate giving slack,
push the rope into the device with
the hand holding the free end, while
pulling out with the hand holding
the climber's side.
3B. Arresting a Fall
To effectively arrest a fall, pull
the free end of the rope fi rmly
downwards.
3C. To feed out rope rapidly
At certain times, in particular when
the leader is clipping the rope, it
may be diffi cult for the belayer to
give slack quickly enough for the
climber. To overcome this, slide the
hand holding the free end up the
rope to the device and manually
hold the cam open, while pulling
the climber's rope through with the
other hand. The hand blocking the
cam must then immediately return
to grip the free end of the rope.
CAUTION, to ensure safety, this
procedure must only be used on a
limited basis and must be executed
quickly. There is a risk for the
belayer's hand to be clenched on
the GRIGRI at the exact moment
of a partner's fall, which results in
him/her losing control of the free
end of the rope.
3D. Precautions to take
- Ensure the safety of the belayer:
it is absolutely essential that
belayers are themselves anchored,
to eliminate the risks of falls of
themselves or their partner.
- Light falls or lightweight climbers:
multiple friction points on a long
run-out will limit the shock-force
transmitted to the device. In
addition, the weight of a light
climber or the load of a sliding fall
may not exert suffi cient tension
on the rope and the locking action
of the device may therefore be
compromised or delayed. For this
reason, always maintain a tight
grip on the free end of the rope.
Caution: Hold only one end of the
rope with each hand. By holding
both ends together in one hand,
as is often done with a fi gure 8 or
Munter hitch, the hand's pressure
on the device may impede its
proper function and thus delay or
prevent the braking action on the
rope.
CAUTION, the device must be able
to operate freely at all times. Its
operation must never be impeded
by any obstacle (fi rst quickdraw,
for example).
Diagram 4. Lowering through
top anchor
To lower a partner without effort,
the GRIGRI remains in place on
your harness as in belaying the
leader. Grip the free end of the
rope fi rmly then use the handle to
unlock the rope.
Braking is effected by loosening
or tightening the grip of the hand
on the free end of the rope.
The handle can assist in braking,
but in no case can it replace the
braking action of the hand gripping
the free end of the rope.
Diagram 5. Belaying the
Second
In this case, the length of the fall
is much more limited. Attach the
device either to the anchor or to
your harness.
CAUTION, the device's operation
must not be impeded by contact
with the cliff. It must not be
jammed into a crack or positioned
with the cam against the rock or
other object. In any of these cases,
it will not function properly.
Diagram 6. Lowering from a
fi xed anchor-point
The free end of the rope must
pass through a carabiner for extra
braking friction. Hold this free end
and push the handle upwards.
Braking is effected by loosening
or tightening the grip of the hand
on the free end of the rope.
Diagram 7. Hauling
This device can replace a pulley-
ascender combination, but
generates more friction.
Diagram 8. Rappeling
This device provides maximum
security for rappels up to 50 m.
Longer descents are not advised
(risk of device overheating).
Rope insertion is done in the
same manner: put the fi xed end of
the rope on the climber's side as
engraved on the device.
- The GRIGRI is an autolock, but
for maximum safety, when holding
the handle, you must never let
go of the free end of the rope. To
descend, fi rst take a fi rm grip on
the free end of the rope. Then, pull
gently on the handle to free the
rope.
Braking and descent control
are effected by loosening or
tightening the grip of one hand on
the free end of the rope.
In order to stop, simply release the
handle.
- For additional braking, pass the
free end of the rope through a
braking carabiner.
- To rappel on one rope and recover
it afterwards, see the diagram.
Caution: descend on the correct
rope or there is danger of death!
Do not forget to tie a stopper knot
in the correct end of the rope
before you descend.
