ABSTRACT:
Improved cam hardware for use with a self-positioning door. The cam is attached to the door mounting post by a threaded connection and has a lower surface which is symmetrically inclined about a high point. The lower surface is contacted by a cam follower roller which is rotatably attached to the door jamb. When the door is opened and released, the cam coacts with the cam follower roller to cause the door to return to its original position where the high point is mated with the roller.
