Abstract
An adjustable frame is slidable front-to-back within slots in cross members rigidly mounted to the box of a panel board assembly, as the last step in the installation procedure, by virtue of lips which allow drawing the frame forwardly into contact with the door frame assembly after it is secured to the box. The frame has slotted holes cooperating with bolts in the cross members, which can be tightened after assembly and adjustment is completed. Panels which mount electrical protective devices or serve as filler plates are trapped in slots formed in sideward-adjustable side rails which are thereafter secured by bolts to the cross pieces.
