Step 1: How to Tie a Klemheist Knot

To tie a Klemheist knot you need “Prusik slings,” which are two lengths of thin cord (preferably 5mm or 6mm in diameter). The thinner the cord is in relation to the thickness of the climbing rope, the greater the ability of the knot to grab the rope. It’s best to make the Prusik slings about two feet long, although some climbers like having one of the slings as long as four or five feet. Buy a five-foot length of thin nylon cord that is specifically made for climbing. Avoid buying spectra cord since it can melt if the knot slips. Tie the ends together with a double-fisherman’s knot, forming a closed loop.

First Step to Tie a Klemheist Knot

The first step to tie a Klemheist knot is to take the loop of cord and place it behind the main climbing rope. Then, after leaving an open loop about 4 inches long at the top and with the knot in the cord at the bottom, wrap the cord around the rope four or five times. Keep the wraps neat and tidy.
