ABSTRACT:
A device for holding a door open having a ready release mechanism to enable the closing of the door has a mounting bracket fixedly attached to a wall. A latch is pivotally supported on the bracket and a release lever is pivotally supported on the latch. An end piece having a ramped outer surface and a flat inner surface is attached to the end of the latch. As the door moves towards the wall to its fully open position, it rides over the ramped surface and is latched open between the release lever and the mounting bracket. The door is released towards its closed position by its riding over a ramped surface formed by the release lever and the end piece.
