Rappelling on the RAD LINE cord

Using the REVERSO and braking capability on small diameter rope. Other rescue systems

Warnings

  • 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.

Incompatibility

The REVERSO is designed for use on single ropes greater than 8.9 mm in diameter, and on half or twin ropes greater than 7.5 mm in diameter.

With the 6 mm RAD LINE cord, the braking capability of the REVERSO is insufficient.

While rappelling, if the user needs to negotiate tricky sections, free a hand and/or untangle the rope, there is a risk of losing control of the rappel.

Even so, there is a way to use the REVERSO with the RAD LINE cord: set up your REVERSO with two braking carabiners.

The advantage of the REVERSO is its simplicity of use, especially for a beginner with poor Munter hitch skills. It also twists the rope less than the Munter hitch.

In any case, using a rappel backup system is recommended.

Rappel braking tests

Good control over the speed of descent. One-handed braking: ok.
