ABSTRACT:
A barrel lock includes a cylindrical plug with a locking ball actuated by a positive acting threaded pin that is screwed into the plug. The plug slips into a mating cylindrical retainer and is locked in place by the pin forcing the ball to protrude beyond tile exterior of the cylindrical plug. An anti-rotation coupling that includes a key attaches to the plug which makes the barrel lock especially easy to install and operate. A threaded puller assures separation of the plug and retainer even when the barrel lock may be jammed due to earlier tampering. The simplicity of the invention provides for a rugged construction with positive sealing surfaces that protect against contaminants and corrosion.
