Abstract: A post coupler includes coupler flanges, reverse bend flanges extending therealong and rounded end projections extending longitudinally from said coupler flanges defining ends of the coupler, the length of the reverse bend flanges being less than the overall coupler length between ends of the rounded end projections.

Abstract: A post coupler is provided with a pair of coupler flanges having rivet receiving apertures for receiving rivets extending from horizontal shelf-supporting beams to facilitate vertical shelf placement in a shelving unit unfettered by the vertical disposition of the post couplers. Apertures in the coupler index with apertures in abutting corner post sections to permit rivet extension therethrough. The reverse bend flanges of the coupler have a length shorter than the overall length of the coupler and wrap around edges of post sections, to be coupled, from the inside to the outside.

Abstract: A post coupler includes coupler flanges, reverse bend flanges extending therealong and tapered end projections extending longitudinally from said coupler flanges defining ends of the coupler, the length of the reverse bend flanges being less than the overall coupler length between ends of the rounded end projections, and the reverse bend flanges preferably oriented along outer surfaces of said coupler flanges.
