Bachmann Hitch: Step 2

Bring the end of the loop around the rope and

through the carabiner.

The Bachmann hitch attaches a carabiner to a rope with
strong cord or webbing so that the carabiner can be used as

a handle. Without a load, the hitch slides freely up the rope.
Once weight is applied, the hitch grips the rope, preventing

the load from slipping back down the rope. The greater the
difference between the diameter of the cord of the hitch and
the diameter of the main rope, the greater the grip of the

hitch. This knot could be used to hang a load from a
vertically suspended rope, such as hanging a food bag while

camping, in which case the weight should be attached to
the loop or sling, not to the carabiner, to prevent slipping.
