Abstract: A wall-mounted shelving system is provided including a wall-mounted track and a cantilevered bracket both based on aluminum extrusions having structural cross-sections and a metal locking pin. The track has a flange member which is periodically machined to accept mounting screws and a web member with through-holes providing for vertical adjustability of the bracket. The bracket is sliced from a special extrusion and machined in the back to slide on to the track. The hook shaped integral part of the bracket allows for the pin to slide through the bracket and position it vertically. The shelving plane slides into the opening between the two cantilevering structural extension members of the bracket and is supported at least at two points without utilizing any positive connection between shelving material and the bracket.
