In canyons, the anchors are not generally linked, in contrast to the chain anchor stations commonly used in rock climbing. Each user must therefore link the anchors to set up an anchor station.
- 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.
Setting up a supplementary anchor system (SAS)
Useful for linking the anchor points at a station, the supplementary anchor system consists of a knotted piece of rope (about 2 m long) and two locking carabiners, carried on the harness.
Linkage for a simple anchor station
Remember to rotate the carabiners once they are installed, to prevent the sleeve from unlocking due to vibration. Adjust the length with a figure eight knot or bowline on a bight.
