Extensions and Tethers:
             The Girth Hitch

             When the extended belay loop configuration is not
             an option, climbers may need to use any number of
             other materials to create an extension or a tether.
             A shoulder-length sling, for example, is too short to
             basket through the harness and then tie an overhand
             knot. Similarly, the extended belay loop may still be
             too short to allow the climber to stand up straight at
             a cliff’s edge. In these contexts a climber may elect to
             use a girth hitch. However, the girth hitch should be
             used with great caution. In failure tests it can behave
             erratically. Sometimes slight twists or rotations of the
             hitch can drastically reduce the material strength of
             the tether, up to 75 percent in some cases. Usually
             these applications are not a concern because climb-
             ers are applying only low loads to the hitch (body
             weight), or they are using the hitch simply to back



















             The girth hitch can be used to attach a personal
             tether, but the tether will not have the same essential
             properties as a belay loop. It is weaker and not
             redundant.
