ABSTRACT:
The invention relates to panels, such as are provided in cabinets or the like. Rabbets are provided in a frame for receiving a panel. Mortises are provided extending in the frame from the rabbets, and rotatable retaining elements are mounted in the mortises. The rotatable retainers are comprised of a ramp encircling them for a portion of their circumference, having one flat circumferential side that is alignable with the side of the rabbet in the frame. Accordingly, upon rotation of the retainer, the ramp, or screw thread, engages the side of the panel away from the bottom of the rabbet, to hold the panel fully against the bottom of the rabbet, independently of the thickness of the panel.
