A lock mechanism for use with a swinging door on hinges with no outside key involved. A fixture is affixed to the door frame opposite the hinges. A through bore allows a rod with a handle at one end and threads at the opposite end to pass through the door and be threaded into a threaded aperture in the fixture to prevent hinged movement of the door. The parts may be cadmium plated for corrosion protection.
