Abstract: A spring clip upright connection for rack shelving includes one upright with tabs and square cutouts and another upright with slots with metal spring clips. As the tabs of one upright are inserted into the slots of the other upright, the uprights are aligned and the spring metal clips open up. When the tabs are fully inserted, the clips latch into the cutouts of the slots of the other upright thereby engaging the upright sections together. This latching prevents one upright from being removed from the other upright while the slots and tabs maintain the appropriate alignment of the uprights.
