The height of the rigging from the top rail of the stretcher to the stretcher line tie-in should be approximately 2 feet. In this method, the long tail of the main line is tied to the victim and the long tail of the belay line is tied to the attendant. An adjusting Prusik is clipped to the attendant's harness to adjust his vertical position with respect to the stretcher. Another Prusik is fitted with a foot loop to release tension on the first Prusik so that it can be adjusted. Small end down is the preferred orientation for the large auto-locking carabiners clipped into the stretcher.
Gates are always in.
It is a three-point anchor system for the main line and belay line anchors. The angle between adjacent legs of the three-point system should be less than or equal to 30 degrees. The length of the outer legs must be 12-15 inches. The LDA uses five locking carabiners from the hardware bags. The locking gates should be on the side away from the rock, and the gate opening should be pointing downhill if possible.
