An upright storage cabinet having a cam lock arrangement which simultaneously locks all of the cabinet drawers. The lock arrangement includes a rotatable cam member which is movable into a locked position wherein the cam member engages a locking element to lift a lock bar into engagement with the drawers, and an unlocked position wherein the cam member disengages from the locking element to disengage the lock bar from the drawers. The cam member is mounted for vertical displacement relative to an actuator of the lock arrangement to allow self-adjustment of the position of the cam member relative to the locking element.
