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.
