Abstract: The vehicle tool tray has a T-shaped based mounted on casters. A vertical post is mounted to the base at the junction of the shaft and crossbar of the Tee. The vertical post is composed of two telescoping sections which are preferably square and tubular in cross section. The telescoping sections are firmly clamped at the desired height by a lock mechanism having a cam and a crank lever pivotally attached to a U-shaped bracket, the cam releasably engaging one of a plurality of slots defined in the upper section of the vertical post. The upper telescoping section of the vertical post is also T-shaped. A pair of short angle irons extend horizontally from the ends of the crossbar of the upper section of the vertical post. The tray is supported on the angle irons and crossbar of the upper section in cantilever fashion. The tray includes a plurality of dividers sectionalizing the top surface of the tray into compartments adapted for holding tools or small parts.
