Ascenders

Ascenders are mechanical devices for ascending on a rope. They are also called Jumars, after a popular brand.

Jumars perform the same functionality as friction knots but are stronger, faster, safer and less effort is needed to use them. A Jumar employs a cam which allows the device to slide freely in one direction but tightly grip the rope when pulled on in the opposite direction. To prevent a jumar from accidentally coming off the rope, a locking carabiner is used. The Jumar is first attached to the climber's harness by a piece of webbing or sling, and then the Jumar is clipped onto the rope and locked. Two ascenders are normally used to climb a fixed rope.
