The Clove Hitch

             The clove hitch is not necessarily used to construct
             an anchor, but it is clearly an anchoring hitch. The
             clove hitch is used to attach a section of climbing rope
             to a locking carabiner, but unlike the figure 8 follow
             through, the clove hitch can be quickly adjusted to


                        The Clove Hitch


               Strength:  The  clove  hitch  is  a  slippery  hitch,
               and it can behave erratically at high loads, when
               the rope is wet, or when interacting with differ-
               ent carabiners. It might be helpful to imagine the
               clove hitch as having the potential to slip at 1,000
               pounds. Actual strength can be quite variable,
               so low loads (like a climber’s body weight) are
               most appropriate for the clove hitch.
               Visual clarity:  The clove hitch’s capturing
               strand is easily recognizable.
               Efficiency: It takes only three quick steps to tie
               a clove hitch, and even after heavy loads it will
               slide off of its locking carabiner.
               Security:  As long as the load applied to the
               clove hitch remains constant and unidirection-
               al, it is quite reliable. However, dynamic loads,
               D-shaped  carabiners, and  wet/icy conditions
               can make the clove hitch less secure.
               Failure mechanism:  The clove can fail in a
               variety of ways. High dynamic loads can cause
               the rope to break right in front of the hitch,
               whereas slower tensile loads can cause the hitch
               to slip.
               Ideal application:  Anchoring the climber/
               belayer to an anchor with a locking carabiner.
