Claim:
A mounting system comprising: a) at least two columns each having a top end and a bottom end with a vertical axis extending therebetween, with said at least two columns defining a first notional wall plane extending between the columns; b) each said column having internal wall portions which together define at least one channel within the column, with each said channel extending substantially parallel to said vertical axis and with each said channel having an outer channel portion opening laterally to an exterior surface of said column and an inner channel portion opening from and extending inwardly from said outer channel portion with said outer channel portion being wider than said inner channel portion, wherein, said internal wall portions comprise a first set of internal wall portions defining each said outer channel portion of each said channel and a second set of internal wall portions defining each said inner channel portion of each said channel; c) one or more mounting brackets each having a first detent member slidably positionable within said channel and engageable with said internal wall portions for fixing each of said mounting brackets against rotation transverse to said vertical axis; d) one or more support beams being substantially aligned with said first notional wall plane, and with said support beams being releasable connected at either of their opposite ends to said mounting brackets, wherein at least one of said support beams is vertically spaced at each of said opposite ends thereof from the bottom end of each of said at least two columns by means of at least one first longitudinal spacer member slidably positionable within the outer channel portion of each of said at least two columns so as to have an upper end portion of said at least one first spacer member in contacting supportable relation with said brackets; and, e) one or more attachment means releasably engagable with the mounting brackets and with the second set of internal wall portions for securing the mounting brackets to the columns in vertically fixed relation.
