Abstract: An upright support member includes at least one laterally extending arm at the upper end thereof. This arm supports upright rails having adjustable hanger brackets thereon. The hanger brackets support door support plates capable of having doors to be treated mounted thereon by hinges whereby the door can be treated on both sides by hinged movement of the door. The door mounting plate can have screw holes that match hinge screw holes whereby to provide substitute hinges for supporting the doors thereon. By means of such structure, a process of painting a series of doors is available wherein the doors are disconnected from their hinges, the hinges being left on the cabinets. Door matching hinges are used and according to the system care does not have to be taken for painting the hinges.
