ABSTRACT:
An adjustable cantilever rack containing means for accurately setting the elevational position of the outer end of the supporting arms. The cantilever rack includes a column of rectangular cross sectional shape, a base secured to the bottom of the column, a load supporting arm and a channel-shaped bracket secured to the inner end of the arm and adapted to fit around the column. Rows of circular spaced apertures formed in the column are adapted to receive bearing pins which are slidably insertable therethrough. An additional pair of apertures are formed in the flange portions of the bracket so that when aligned with the apertures in the column, a gap exists between the web portion of the bracket and the column. A pair of set screws are threadedly engaged with a corresponding pair of threaded apertures in the web portion of the bracket below the supporting arm for adjustably controlling the width of the gap and thereby adjustably controlling the elevational position of the outer end of the supporting arm.
