A key component of a rappel technique developed by our Tactical Rappel Class instructors, our 8 Link allows you to extend your Figure 8 descender further away from your harness to make room for a back-up Prusik hitch below the descender. Quickly attaches using a girth hitch. Multiple carabiner slots allow proper length adjustment. Pocket stitching breaks at 5 kN (1,100 lbf). MBS: 16.9 kN (3,800 lbf) (Rappel 8 descender not included).
