Disposable Locks

Aluminum body, Alumoweld shackle and aluminum screws 

The screws break away at a consistent torque leaving a smooth surface. The alumoweld shackle has the strength of the steel core and the corrosion protection of the aluminum cover jacket. The two screw model has been tested to over 1,200 pounds without failure.
