A tool for temporarily holding a second framing member to be fastened into a frame assembly parallel to a first framing member that is already fastened into the assembly. It has a track 1 with a first fixed clamp plate 2 on one end and a second movable clamp plate 11 on the other end; a slide bar 20 mounted on the track between the first and second plates; third 21 and fourth 29 fixed clamp plates on respective ends of the slide; and a clamp closing device 15 that moves the second plate inward toward the fourth plate. A second workpiece 32 between the second and fourth plates will be clamped between them, and will push the slide toward the first plate, simultaneously clamping a first workpiece 31 between the first and third plates.
