               GENERAL RIGGING CONSIDERATIONS


               Orientation of Carabiners in Rigging
               Consistently orienting carabiners in the same manner during rigging provides efficiency
               and reliability for a secure connection point.  A recommended practice is to hook a
               carabiner into a connection point in a downward motion and rotate the body around so

               that the gate is facing upward with the nose of the gate oriented away from the

























                 Figure 66- Orientation of carabiners in rigging

               connection point (Figure 67).  This procedure places the spine against the ground and
               keeps the gate accessible for rigging and visual inspection.

               NOTE: Be cautious that this manner of rigging, when untensioned and then tensioned
               again with a suspended carabiner, can promote diagonal rigging of the carabiner,
               resulting in 50-60% strength loss.  In such cases, rotation of the heavier gate downward

               can be appropriate, however it should be away from terrain.


               CARABINER RIGGING


               •  For safety at a critical rig point, consider using one locking carabiner or two non-
                   locking carabiners that are placed with their gates opposite and opposed.
               •  Tension along the major axis of a carabiner- be aware to prevent the primary force
                   going onto or across the minor axis (cross-gate forces).
