Rat Claw - Part 1
This shows the design for the rat claw, how to make it is self explanitory. I have not seen cargo straps used, but I would practice with it before I "field tested" it. A Humvee door is pulled off using the Rat Claw, a flat steel hook developed by 2nd Brigade Combat Team, 10th Mountain Division (LI) Safety Officer Bill Del Solar. Del Solar developed the Rat Claw to aid in extrication of Soldiers from Humvees when the doors are damaged or wedged shut.
