Abstract: A door and hinge apparatus allowing quick connection and disconnection with respect to a frame, such as a cabinet frame. The door includes at least two generally elliptical slots. The generally elliptical slots have an enlarged opening and a narrower slot portion located above the enlarged opening. Mounting posts having enlarged heads protrude from one hinge leaf. The door attaches by placing the enlarged openings over the enlarged heads and sliding the door to engage the narrow slot portions with the enlarged heads. An aperture in the second hinge leaf aligns with an aperture associated with the door, and a locking plug is inserted through both apertures to prevent the door from sliding off the mounting posts.
