The CLUTCH™ is designed to provide safe rope slip in overload situations. To assess the point of slip across a wide variety of industry ropes, the device was anchored, and various ropes were pulled through the device at a rate of ~15cm/min.
Across the thirteen 10.5-11mm industry ropes tested, the 11 mm CLUTCH achieved safe and reliable slip between 7.3kN and 11.56kN.
In all cases, no visible damage to the rope or device was observed as a result of the slip event.

For each rope type, a minimum of two samples from a single lot of new rope was tested in a controlled laboratory environment.
CLUTCH slip behavior is influenced by many factors including lot-to-lot rope variability, variation in rope diameter, rope and device wear, environmental conditions, etc.
Fully read and comprehend the CLUTCH Manual prior to use in any rigging scenario.
Obtain professional training to industry standards prior to CLUTCH testing/application.
Consult a qualified technician or trainer before attempting techniques on your own.
