Abstract: A lock for a cabinet of the type wherein a door of the cabinet is movable through a frame of the cabinet is provided. An exemplary lock of the present invention includes a first and second restraining member connected by a rod and rotatable around an axis of rotation between a first position wherein a cabinet member is trapped between the restraining members and the door can not move through the frame and a second position wherein the door is freely movable through the frame. The lock optionally includes a mounting member having a rod-retaining section and optionally one or more rotation locks and/or one or more rotation restraints. The restraining members are optionally sized and shaped to facilitate rotation between the first and second position while accommodating different sizes and specifications of cabinet types. The lock optionally includes one or more strengthening members and end extensions angled on one or both ends of the rod.
