How to Tie a Bachmann Knot for Climbing

A Bachmann knot is a popular knot for climbers to use. It's a friction knot that is used when ascending vertical or hanging lines. The Bachmann knot releases easily and is also used for grasping when ascending a rock face. Follow these steps to learn how to tie this knot.

Difficulty: Easy

Instructions

1. Make a loop from a small piece of rope using a double overhand knot. To make a double overhand knot, pass one end of the rope over the center of the rope two full turns, then pass is back through the turns and pull tightly.

2. Hold a carabiner against the main climbing rope. The carabiner must be a locking carabiner. Check the main rope for frays and defects.

3. Pass the loop around the main climbing rope and through the carabiner. Make three complete turns, checking to be sure that each turn is done neatly.

4. Insert the knot into the loop. Pull it downwards in the direction that you expect the weight to be.

5. Test the Bachmann knot before climbing. Check that it grips and releases easily.

Tips & Warnings

• The rope that is used to make the loop in Step 1 should be smaller than the climbing rope. The closer the two ropes are in size the less effective the Bachmann knot will be.
• Using a rope in poor condition can result in injury or death. Always check that your rope is in good condition before use and after tying the Bachmann knot.
