Abstract: A locking fence for a power tool such as a chop saw, or for a work surface of a workbench, is capable of being moved to a selected location on the chop saw base or work surface and oriented at a selected angular orientation relative to the chop saw blade. The fence is locked simultaneously in such location and orientation when an operator rotates a cam actuator to lift a first clamping member away from the fence, which in turn draws a second clamping member into clamping engagement with the underside of a workpiece support of the base, and which further forces a cam portion of the actuator against the fence. No tools are required to lock or unlock the fence. The fence defines an arcuate slot for enabling the angular orientation to be adjusted. The arcuate slot is maintained in juxtaposition to a slot formed in the work surface for enabling movement of the fence to its selected location on the workpiece support or work surface, by linking screws linking the slots.
