A work support apparatus includes a pedestal, a mounting block, and a plurality of fasteners disposed on the pedestal to interconnect the mounting block to the pedestal. The fasteners are mounted to the pedestal and include a locking mechanism extending outwardly from the pedestal. The mounting block defines a plurality of bores extending through the mounting block for receiving the locking mechanism of the fasteners therein. The mounting block may be oriented in several different orientations by positioning the mounting block on different groups of fasteners. The locking mechanism of the fasteners includes a wedge pin which extends through the bore of the mounting block for selective engagement by an actuator to release the mounting block from the fastener.
