A door hold open device is disclosed for maintaining a door swingably mounted on a door jamb in an open position. The door hold open device includes an elongate track housing mounted on the door jamb, and a shaft disposed within the track housing. The shaft extends along a horizontal axis and is mounted for free rotation about the axis. A slider block having a threaded bore threadably engages a threaded portion of the shaft. The slider block is capable of moving linearly along the horizontal axis and causes the axial rotational movement of the shaft as it moves linearly from side-to-side. An arm link is pivotally connected at one of its ends to the slider block and pivotally connected at its other end to the door. The arrangement is such that upon manually opening and closing the door, the arm link moves the slider block linearly from side-to-side thereby causing the axial rotational movement of the shaft. A clutch mechanism is disposed adjacent the shaft and is selectively engagable with a non-threaded end of the shaft for preventing the rotation of the shaft thereby locking the slider block in a stationary position for maintaining the door in an open position.
