What is the function of a Prusik knot in a rope system?

• A. Progress capture and ascending on a loaded rope; it also serves as a backup friction hitch.
• B. Acts as a stopper knot for the rope.
• C. Locks a carabiner in place.
• D. Creates a fixed anchor point.

Answer: (A)

The main idea is that a Prusik knot works as a friction hitch that grips a rope when it is loaded, allowing you to move along a rope or hold your position without sliding down. When you apply upward force, the wraps bite into the rope and prevent slipping, which lets you progress up the line or stop a fall as part of a backup in a rope system. When there’s less or no load, the knot can slide more easily, so you can adjust or reposition as needed. This makes it useful for progressing on a loaded rope and as a backup friction hitch in case other devices fail. It isn’t a stopper knot, it doesn’t lock a carabiner, and it doesn’t create a fixed anchor point.
