The present invention is directed towards an auxiliary hand table which is removably mounted to a main surgical table. The hand table is mounted, via first and second mounting devices, to the rails provided on each side of the main surgical table. The first mounting device includes upper and lower jaws, the upper jaw being provided with a fastener to positively attach the device to the rail. The second mounting device includes a pair of interconnected hook-shaped members which are hooked over the opposite rail. The second mounting device further includes a series of mounting studs which facilitate attachment of a hand table support structure, thereby supporting the hand table. The vertical position of the hand table relative to the main table is adjusted by altering the mounting position of the support structure to the second mounting device. A tensioning bar interconnects the mounting devices, one end of the bar being received by an elongated bore provided by the first mounting device. Adjustment of the tension between the devices is accomplished via a tensioning device which is threadably mounted to the first mounting device and engages an end of the tensioning bar. As the tension between the first and second mounting devices reaches the desired amount for correct mounting of the hand table, the terminal end of the hand table moves slightly upward relative to the main table, providing visual indication that the hand table is properly mounted.
