1. Field of application
Personal protective equipment (PPE).
Ventral rope clamp for ascending rope.
- Rope clamp for mountaineering and climbing (EN 567: 1997).
- Ascending device for the work rope (EN 12841 type B: 2006).
This product must not be loaded beyond its strength rating, nor be used for any
purpose other than that for which it is designed.
WARNING
Activities involving the use of this equipment are inherently dangerous.
You are responsible for your own actions and decisions.
Before using this equipment, you must:

the practices defined in the Field of Application.
This product must only be used by competent and responsible persons, or those
placed under the direct and visual control of a competent and responsible person.
Gaining an adequate apprenticeship in appropriate techniques and methods of
protection is your own responsibility.
You personally assume all risks and responsibilities for all damage, injury or death

take this risk, do not use this equipment.
2. Nomenclature of parts
(1) Chest strap attachment hole, (2) Cam, (3) Safety catch, (4) Harness attachment
hole, (5) Wear plate.
Principal materials: aluminum alloy frame, stainless steel cam and wear plate.
3. Inspection, points to verify
Before each use
Verify that the product is free of cracks, deformation, marks, wear, corrosion, etc..
Check the condition of the frame, the connection holes, the cam and safety catch,
the springs and the cam axle.
Check the movement of the cam and the effectiveness of its spring.
Make sure the cam's teeth are not clogged.
WARNING, do not use this rope clamp if it has missing or worn-out teeth.
Consult the details of the inspection procedure to be carried out for each item of PPE
on the Web at www.petzl.com/ppe.
Contact Petzl if you have any doubt.
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.
WARNING:
- foreign bodies which can impede the operation of the cam,
- situations where the safety catch can snag and cause the cam to open.
4. Compatibility
Verify that this product is compatible with the other elements of the system in your
application (compatible = good functional interaction).
Connectors
Make sure your connectors are compatible with the rope clamp (shape, size, etc.).
Use an OMNI, or a DELTA quick link, or a DEMI-ROND quick link.
5. Function principle and test
This rope clamp is a device for ascending rope. It slides along the rope in one
direction and jams in the other direction.
The cam's teeth initiate a clamping action that pinches the rope between the cam
and the frame. The slot in the cam allows mud to be evacuated.
6. Installation on the harness
Attach the device to the harness by passing a quick link or an OMNI through the
connection hole.
Fasten the chest harness to the upper hole, so that the device is held in a vertical
position against the chest.
Close the CROLL's cam when not in use because equipment or other objects can
become jammed in the device if left open.
7. Installing and removing the rope
Pull the safety catch down and lock it on the frame of the device. The cam is thus
held open.
Put the rope in the device. Pay attention to the Up/Down indicator. Operate the safety
catch so that the cam presses against the rope. In this position the safety catch helps
prevent involuntary opening of the cam.
To remove the rope
Move the device up the rope while opening the safety catch to disengage the cam.
8. Rope ascending
Use the CROLL with another rope clamp (BASIC, for example) and a foot-loop.
Always attach yourself to the second ascender with an appropriate lanyard.
Angled traverse situation
Starting on an angled rope: put a leg over the rope to make its angle parallel to the
CROLL's rope channel.
9. Short rope descent
Gently slide the device up the rope and simultaneously push down on the cam
with the index finger. Do not manipulate the safety catch because there is a risk of
accidentally opening the cam.
10. EN 12841 type B - additional information
The CROLL is a type B rope adjustment device used to ascend the work rope.
The CROLL must be used with a type A backup device on a second
(safety) rope (e.g. with an ASAP mobile fall arrester for rope).
The CROLL is not suitable for use in a fall arrest system.
- To meet the requirements of the EN 12841: 2006 type B standard, use 10-11 mm
EN 1891 type A semi-static ropes (core + sheath). (Note: Certification testing was
performed using BEAL Antipodes 10 mm and 11.5 mm ropes).
- Use a connecting assembly of maximum length 1 m (lanyard + connectors +
devices).
- To reduce the risk of a free fall, the rope between the rope adjuster and the anchor
must always be taut.
Do not allow the safety line to be loaded when the working line is under tension.
A shock-load can damage the belay line.
Nominal maximum load: 140 kg.
Warning: for workers weighing over 100 kg, consult our information on Solutions for
workers over 100 kg on our web site
www.petzl.com.
11. Supplementary information regarding
standards EN 365
Rescue plan
You must have a rescue plan and the means to rapidly implement it in case of
difficulties encountered while using this equipment.
Anchors
The anchor point for the system should preferably be located above the user's
position and should meet the requirements of the EN 795 standard (minimum
strength of 10 kN).
B16 CROLL
Various
- In a fall-arrest system, it is essential to check the required clearance under the user
before each use, to avoid any impact with the ground or an obstacle in case of a fall.
- Make sure that the anchor point is correctly positioned, in order to limit the risk and
the height of a fall.
- A fall arrest harness is the only device allowable for supporting the body in a fall
arrest system.
- When using multiple pieces of equipment together, a dangerous situation can result
if the safety function of one piece of equipment is affected by the safety function of
another piece of equipment.
- WARNING DANGER, take care that your products do not rub against abrasive or
sharp surfaces.
- Users must be medically fit for activities at height. Warning, inert suspension in a
harness can result in serious injury or death.
- The instructions for use for each item of equipment used in conjunction with this
product must be respected.
- The instructions for use must be provided to users of this equipment in the
language of the country in which the product is to be used.
