Can we rely on devices to slip on ropes at predictable forces given the possible range of physical and environmental conditions? Here we test the Petzl Shunt on several different ropes.
Details of a set of tests on 6061-T6 aluminium cantilevered tubes assessing the relevance of theory to observed test results.
A new set of tests checking the strength of some Nylon and Dyneema climbing slings which are more than 10 years old.
One piece of information often lacking in discussion of the Petzl ASAP is just how much rope is needed below the device to be sure it catches during a fall.
Absorbica L64 & L57 energy absorbers. How far do they extend? What is the force required to "tear" them open?
