Petzl Rack – Variable friction descender with braking bars.
This rack updates the classic brake bar descender. The design and configuration of the bars makes it easy to set up and insert the rope. Compact and lightweight, the device allows the user to adjust the amount of friction during the descent to adapt to changing conditions (rope weight, terrain,etc. ). The number of bars engaged on the rope may be adjusted at any time to obtain the desired amount of friction
Good distribution of friction and heat helps preserve the rope. Does not twist the rope.
