The door control mechanism comprised of cam latch members on opposite ends of a rotatable shaft connected to a pivoted door by bearing members, and keeper members secured to the door frame adjacent edges of the door that are transverse to the pivotal axis of the door. Rotation of the shaft about its longitudinal axis engages and disengages the cam and keeper members. The cam members include a body portion having a forked tine portion projecting from one side of the body, and a single tine portion with an inclined side surface projecting opposite therefrom. The keeper members include a base portion having a post projecting from the base for receiving the forked portion of the cam, and a post having an inclined side wall and cam latch retaining member for receiving the single tine portion of the cam.
