Shelf Pin Ledger Support Rail
A 160 mm ledger rail that plugs into five standard 5 mm shelf-pin holes on 32 mm System-32 pitch and spreads a sagging shelf's load along the whole cabinet side instead of four little pins. The 14 mm deep ledge carries the shelf, gussets under every pin put the load in the XY print plane, and M4 clearance holes let you screw through the web into the cabinet side (rescue for blown-out pin holes) or up into the shelf itself.
