<p>A partially thinned wire support pad (12, 22, 30) of a generally rectangular shape is provided extending laterally from a longitudinal edge of a base plate of a load beam (10, 20, 28). The support pad (12, 22, 30) is cut from sheet material in one piece with the load beam (10, 20, 28) and, during other manufacturing procedures applied to the load beam (10, 20, 28), is partially thinned to a thickness less than the thickness of the load beam (10, 20, 28). In addition to the partial thinning procedure, a smooth radiused convex edge (14, 24) is provided for the exterior perimeter of the partially thinned wire support pad (12, 22, 30). Partial thinning may also be provided to a trough (34) at a base of channel rails (32) to provide an area of reduced thickness to the channel (32) to provide proximal and distal edges of the channel (32) having a smooth well-radiused profile.</p> |
