The Petzl Jag System is an enclosed 4:1 progress capture pulley system that can be used for hauling, tensioning a system, pickoffs, making a releasable anchor, or evacuating a victim when paired with an I'D Descender. The Jag and Jag Traxion that create the system utilise sealed ball bearings to increase efficiency up to 91%, which with the 4:1 mechanical advantage, enable easier work to be done by the user.
Established in 1977
