Shelving feet for "boltless" shelving from Global Industrial and others

These are some feet I made because I forgot to order some for the shelving I recently purchased from Global Industrial Supply. These "rivet" style bolt less shelving units are quite common and sold under many brand and house names (Interlake Mecalux style). These feet should fit any shelves with uprights that are ~ 55 x 44 mm
