Rockler’s Speed-Cope™ is a heavy-duty jig for making cope cuts for tight-fitting overlapped joints in crown and base molding when used with a power jigsaw. It accommodates molding up to 7-1/4” wide and adjusts for 45- and 90-degree inside miters, as well as chair molding, panel molding and more. The base supports most jigsaws, and the SpeedCope mounts on benchtops or sawhorses.
