Precautions when using the ZIGZAG


  • Read the technical notice before viewing the following techniques.
  • It is important to fully understand the information provided in the technical notice before using this complementary information
  • Mastering these techniques requires training.
  • Consult a professional before attempting to perform these techniques on your own.

Note: in this document the name ZIGZAG means either the ZIGZAG or ZIGZAG PLUS models.

Release lever

Any accidental pressure on the ZIGZAG's release lever can cause a fall.

Verification during use

Beware of foreign bodies or system elements which can impede the operation of the friction chain or press on the release lever: branches, retrieval balls, rope terminations...

The ZIGZAG is for use with EN 1891 rope, 11.5 -13 mm in diameter. Storage: Depending on the techniques used, the ZIGZAG can be left in place on the rope to save time on the next use.

Connector between ZIGZAG and CHICANE

The shape of the CHICANE’s attachment hole is optimized for OK and Am’D. This shape prevents the connector from rotating, which could create a risk of dangerous interplay between the CHICANE and the ZIGZAG’s release lever.

Rope glide and rope length in double mode use

When the rope slides through the ZIGZAG (ascent or descent), the rope also slides around the anchor.

If rope glide is slowed by friction in the anchor, or on branches, movement will be less fluid.

Using doubled rope makes it difficult to evaluate rope length in relation to tree height.
