A clamping device for clamping a straight edge to a board to hold such straight edge in place during use thereof. Two clamping members are moveably interconnected to opposite ends of a shaft which extends through an aperture in a bearing member. The bearing member is connected to the straight edge, and the shaft moveably extends through such aperture. The clamping members are provided with locking means, and when such means are operatively locked one clamping member engages and exerts a compressive force against one surface of a board and the other clamping member engages the bearing member to thereby exert an opposing compressive force to lock the straight edge in place.
