The Menace Garage Lock-MGL is mounted to each side of the door, and the abutting door frame is equipped with the dead bolt receiver or housing, a one-quarter inch cast steel plate bolted to the frame, with a U-shaped bracket into which the dead bolt slides. The dead bolt is cylindrical and possesses the unique characteristic of rotating freely upon its longitudinal axis, which means that even if a thief attempted to saw through it with a hacksaw blade, the dead bolt simply rotates, and thus cannot be cut.
