Y-lanyard with a knotted JANE
- Carefully read the Instructions for Use used in this technical advice before consulting the advice itself. You must have already read and understood the information in the Instructions for Use to be able to understand this supplementary information.
- Mastering these techniques requires specific training. Work with a professional to confirm your ability to perform these techniques safely and independently before attempting them unsupervised.
- We provide examples of techniques related to your activity. There may be others that we do not describe here.
A JANE can be knotted to form a Y-lanyard for progression and/or work positioning.
A figure-eight knot must be tied into the harness attachment point.
The short arm must measure no less than about 10 cm (without connector).
Ideally, the knot in the JANE should be tied into the metal attachment point of the harness.
Petzl has noted that some users tie directly into the harness textile attachment point. In this case, the (textile) lanyard rubbing against the (textile) attachment point can result in a high level of wear. A detailed inspection of the condition of the harness and lanyard must be done after each use and may lead to the retirement of the worn components.
Follow the Instructions for Use for the JANE, your harness, and all of your equipment.
Limit the potential for a fall:
The JANE is not an energy absorber, but its dynamic capacity allows it to absorb short falls (see table). The tightening of the knot also contributes to shock absorption: the knot should loosened on a regular basis.
