What is the function of a Prusik in rope rescue systems?

• A. Quick-release device
• B. Friction hitch used for progression capture, backup, or control
• C. Load cell
• D. Tatting device

Answer: (B)

A Prusik is a friction hitch that bites the rope to give you controlled grip and movement. It works by tying a loop of cord around the main rope so that when you load it, the hitch tightens and grips the rope, allowing you to ascend, descend, or hold/stop movement in a rescue setup. When the load is relaxed, it loosens and can slide, making it easy to reposition. In rope rescue, you use it for progression capture (moving along the rope with a backup in place), as a backup or safety device to arrest a fall, or as a control mechanism to modulate speed during lowering or hauling. It’s not a quick-release device, since it relies on friction to hold rather than an automatic release. It isn’t a load cell, which would measure force, and it isn’t a tatting device, which is a lace-work technique unrelated to rope rescue.
