The PSDR wave hanger can accommodate cabinet doors with hinge holes up to 36 in apart. They are custom-fit to the size of the Pro Drying Rack SD Series poles for minimum swing, allowing you to hang cabinet doors and parts closer together. The PSDR's 18 ft of drying line is enough space for drying up to 50 cabinet doors. The PSDR Series with hinge hooks or EFC hooks provides ideal and completely unmarred surface results. Hinges hooks are placed in the cup holes and then fit over one of Paint Line's hangers for all-sides spraying and drying. Cup-hooks can also be screwed into the tops and bottoms of cabinet doors to be hung and sprayed. After painting on the spinner assembly, the door on the hanger is simply transferred over to the drying line where it will hang until ready for door hardware and installation.
