Abstract: The invention relates to the construction of metal articles such as work benches, pallet racks, etc., by way of example. In a typical construction upright hollow metal legs are secured to a flat table or platform surface. The upright members or legs preferably may be square in cross section. The upper ends of the legs are secured to mutually perpendicular transverse members which in turn are secured to the flat platform surface. The transverse members are preferably channel shaped with side flanges. An end plug or fitting is inserted into the upper end of each leg, the fitting being tapped to receive stud bolts. The ends of the transverse members are secured to the legs and the end plugs by stud bolts.
