Use the Prusik Hitch to secure a loop to a tight line. It slides when not weighted along a tight rope but jams solidly upon loading. Mountaineers use this knot to form footholds to help them climb a vertical rope and also for belay systems. Many climbers believe that the Prusik Knot has more "give" resulting in a reduced force applied to the system in the case of a shock load (a fall), as opposed to a similar purpose knot such as the Klemheist. Because the knot is tied in smaller diameter cordage a little give or slippage in the knot may be better than a knot that holds tighter, which in the case of a belay system taking a shock load might increase your chance of a catastrophic-system-failure. The loop needs to be made in rope or cord that is at most half the diameter of the main line.
Prusik Hitch Knot Tying Instructions
- Make a sling of cordage (no more than 1/2 the diameter of main rope).
- Tie a Girth Hitch around the main rope.
- Pass the loop of the sling back through the center of the Girth Hitch three or four more times.
- Load with weight to make sure it
