Abstract: A U-shaped member having an aperture in the bottom wall thereof and axially aligned apertures in each of the side walls at a point remote from the bottom wall is placed over the edge of a panel such as a sheet of composite board intended to be used as the back of a chair. The U-shaped member carries a nut on the inside surface of the bottom wall in line with the aperture and is securely held in place on the edge of the panel by a rivet passing through the apertures in the side walls and a hole drilled through the surface of the panel. An article such as a portion of the chair frame is secured to the edge of the panel by an elongated bolt which passes through the frame, through the aperture in the bottom wall of the U-shaped member and which is then screwed into the nut being held in place by the U-shaped member. The free end of the bolt enters a hole previously drilled into the edge of the panel in axial alignment with the nut and the aperture in the bottom wall of the U-shaped member.
