Building a window box or flower box? Putting a bird house together? Perfect for medium-sized, complex projects, our CT36 clamp attaches to your work surface and to the workpiece itself, allowing you to get a square frame easily and set larger glue-ups to dry. You no longer need to use c-clamps and stabilizing wood frames, to keep it from bowing, and sanding is a breeze, with the workpiece stabilized while you work. Say goodbye to unwieldy and complicated! Say hello to DONE.
