A radium release hitch is a load-releasing hitch using 3:1 mechanical advantage which is used in a two-rope technical rescue system. The Radium Release Hitch allows a load to be transferred from one rope to another and is commonly rigged into the belay line prior to the operation of a two-rope technical rescue system.

A radium release hitch is typically tied with 10 meters of 8mm rope and two locking carabiners. A reasonable length for the hitch (distance between the 2 carabiners) is 10 to 15 cm.

History

The Radium Release Hitch was developed by Kirk Mauthner (who lives near Radium Hot Springs, hence the name) as a result of the extensive comparative analysis of release devices undertaken during 1997 through 1999
