WARNING: Activities involving the use of this equipment are inherently dangerous. Users are responsible for their own actions and decisions. Always read and understand all instructions for use, receive specific training, understand the equipment's capabilities and limitations, and accept the associated risks. Failure to heed these warnings may result in severe injury or death.
This product must only be used by competent and responsible persons, or those under the direct visual supervision of a competent and responsible person.
1. Field of Application
Personal Protective Equipment (PPE) for fall protection from height. Backup device for rappel activities.
This product must not be pushed beyond its limits or used for any purpose other than that for which it is designed.

- (1) Frame
- (2) Cam
- (3) Springs

3. Inspection, Points to Verify
Petzl recommends a detailed inspection at least once every 12 months. Intensity of use may require more frequent inspections. Follow procedures described at Petzl.com and record results.
Before each use:
- Verify the product for cracks, deformation, marks, excessive wear, or corrosion.
- Verify the presence and proper function of the springs.
- Check the cam's mobility.
- Ensure no foreign objects are in the mechanism.
During each use:
- Regularly monitor the condition of the product and its connections to other system equipment.
- Ensure all system equipment is correctly positioned relative to each other.
4. Compatibility
Verify compatibility with other system elements. The SHUNT works on single or doubled EN 892: 2016 or EN 1891: 1998 type A ropes:
- 8 to 11 mm: use two strands of the same diameter rope.
- 10 to 11 mm: you can use a single strand of rope.
Warning: Certain ropes may be slippery and reduce the SHUNT's braking effectiveness (e.g., new ropes, ropes with sheath treatments, wet, frozen, or muddy ropes). Perform a function test.
Ensure the connector is always loaded on its major axis.
5. Working Principle
The SHUNT slides along the rope. If the cam is loaded, it pinches the rope in the rope channels, and the device locks onto the rope. The cam and frame must always be able to rotate freely.
Warning: Any pressure or interference on the cam or device will prevent it from locking. Do not grip the SHUNT with your entire hand.
6. Installing the SHUNT
Follow installation methods. Perform a function test during installation to verify the device locks on the rope in the desired direction.
7. Uses
Rappel backup: Attach the SHUNT below your descender.
Unlocking under load: Pull on the rope below the SHUNT and align it with the axis of the rope.
8. Additional Information
