ONE TYPE OF CABINET WING INCLUDES A GENERALLY U-SHAPED FLANGE THAT FITS AROUND AND CLAMPS ONTO THE EDGE OF THE CABINET FRAME WITH ONLY A SINGLE SCREW REQUIRED TO SECURE THE WING TO THE FRAME. THE CABINET AND DOOR WINGS MAY INCLUDE A SELF-CLOSING MECHANISM HAVING A HOUSING SECURED TO OR INTEGRAL WITH THE CABINET WING, THE HOUSING CONTAINING A SPRING-BIASED CALM THAT IS URGED OUTWARDLY TO ENGAGE THE KNUCKLE OF THE DOOR WING, AND A HINGE PIN OR PINTLE DEFINING THE AXIS OF THE DOOR. THE DOOR WING KNUCKLE INCLUDES A CUT-OUT PORTION COOPERATING WITH THE CAM TO URGE THE DOOR THROUGH THE LAST FEW DEGREES OF THE ARC OF CLOSING MOVEMENT AND YIELDABLY RETAIN THE DOOR CLOSED.
