An adjustable clamping device for use in temporarily securing together opposed stairway stringers about one or more stair tread members includes a body member having opposed upper and lower ends. A length adjustable first arm is connected to the body member upper end and a length adjustable second arm is connected to the body member lower end. The clamping device includes a pressure plate having a generally planar configuration and situated parallel to the body member. An actuator having a first portion is operatively coupled to the body member and to the pressure plate to selectively move the pressure plate between retracted and extended configurations. A user input is attached to a proximal end of the actuator by which a user may operate the actuator to move the pressure plate.
