Knot Passing During Lowering – Piggyback & CMC Harken Clutch

The Lowering Piggyback Method is a refined technique used in technical rope rescue to manage knots effectively while maintaining continuous control over the descent. This method is particularly useful when using descent control devices such as the Clutch, MPD, or Maestro and requires a secondary descent control device and rope. The following steps outline how […]
