Rope

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.
