RAD – Rope Adjustment Device


The RAD evolved from our A-B Descender to be a smaller, lighter and more versatile device. It is ideal as a second descender or a spare for emergency use.

The RAD can be used in conjunction with a rope lanyard to form an adjustable work positioning lanyard (EN358). It may also be used as a stand-alone rope adjustment device (EN12841-C, descender), or a belay device (EN15151;Type 6).
