Video - Make a Purcell Prusik

Purcell Prusik

A Purcell Prusik is an adjustable tether used by climbers to connect an anchor. This simple solution is easy to create and preferable from a safety perspective to many commercial products. It is especially useful for climbing instructors and guides who need a versitile and easy to adjust system for personal anchoring. It is also valuable in many rescue situations.

We present this primarily for use as a personal tether rather than for the ascention use shown towards the end of the video.

 

Thanks to Tree Climbing Etc for creating this video turtorial.

A good written guide to tying a Purcell Prusik is in Climbing Self Rescue: Improvising Solutions for Serious Situations (which should be on every professional and serious climber's bookshelf already). Rigging for Rescue has a LOT more information on Purcell Prusiks and safety in "An Examination of Purcell Prusik as Personal Restratint Lanyards."


sterling rope chain reactorIf you don't like the Purcell Prusik, the Sterling Rope Chain Reactor is OSI's second choice as a personal safety tether. We like for it’s full strength loops and the fact that it is made of nylon webbing. While a little heavier and bulkier than spectra, nylon will stretch to absorb a little more fall force.
