The vertical walls of a sheet metal cabinet comprise front and back members each having a generally U-shaped horizontal cross-section and side members connected between the U-shaped front and back members. The wall members are connected by interengaging slots and tabs on inwardly extending abutting flanges. One flange of each pair of abutting flanges is provided with a series of slots which serve to support shelves within the cabinet. Gussets located at the corners of the cabinet serve to secure legs to the cabinet and also to prevent disengagement of the wall members by locking the wall members against relative vertical movement. A counter top is secured to inwardly extending flanges at the upper edges of the cabinet walls by clamps which bear downwardly on upwardly facing surfaces secured to and spaced below the counter top. The clamps are secured to the flanges of the wall by screws the shanks of which press upwardly against the underside of the top.

A sheet metal cabinet having four vertical walls comprising a front wall, two side walls extending perpendicularly from the front wall in the rearward direction, and a rear wall extending from one side wall to the other side wall in perpendicular relation to the side walls and spaced rearwardly from the front wall, the intersections of adjacent walls forming corners of the cabinet and each wall having a pair of vertical edges located at corners of the cabinet, said walls comprising a first sheet metal element forming at least part of the front wall and having integral, rearwardly extending side portions extending perpendicularly from the opposite vertical edges of the front wall, each rearwardly extending side portion forming a part of a side wall of the cabinet; a second sheet metal element forming at least part of the rear wall and having integral, forwardly extending side portions extending perpendicularly from the opposite vertical edges of the rear wall, each forwardly extending side portion forming a part of a side wall of the cabinet; a third sheet metal element forming part of a side wall of the cabinet and extending from one side portion of the first element to the side portion of the second element on the same side of the cabinet, said third element meeting the side portions between which it extends along vertical lines, a fourth sheet metal element forming part of a side wall of the cabinet and extending from the other side portion of the first element to the side portion of the second element at the same side of the cabinet, said fourth sheet metal element meeting the side portions between which it extends along vertical lines; each of said side portions having an integral flange extending inwardly in a vertical plane perpendicular to the side walls, and located adjacent the vertical lines at which it meets an edge of said third and fourth elements; each of said third and fourth elements having integral flanges extending inwardly in vertical planes perpendicular to the side walls and located adjacent the vertical line at which it meets the side portion of the first and second element, the flanges of the element meeting at said vertical lines being in abutment and being secured together by connecting means comprising a series of interengaging slots and tabs, the tabs on any given flange extending vertically in the same direction whereby connection of the abutting flanges is accomplished by horizontal movement of the tabs into the slots followed by relative vertical movement of the abutting elements.
