Abstract: An overhead opening door lock device for use with existing types of door systems having horizontally hinged panels carried on rollers confined within channeled roller tracks is attached on the interior side of the door and fixes the door in position relative to the roller track. One leg of a U-shaped device is inserted in the hollow interior of a tube that serves as an articulation axis for a pair of hinged panels. The other leg of the U-shaped device penetrates a suitably positioned aperture in the web of the adjacent channeled roller track. A shear pin or padlock shank may be inserted through an aperture in a tip portion of the other leg that projects past the outside plane of the roller track web.
