What is a Prusik? Prusik is mainly used as a rope grab to attain progress capture in a rope system, normally a Mechanical advantage system. A Prusik is simply a thin piece of chord or webbing tied into a loop normally with a double fisherman’s knot. The Prusik is then tied onto the thicker rope in such a way that it will not slide down the rope when loaded by pressure.
