Plunger Tube Assembly including the Upper Chuck Jaws for Delta and Rockwell 24 inch Scroll Saws. Also 430-02-628-0006. We improved the wall thickness on our version to prevent the Chuck Jaws from tearing out the bottom portion of the tube. Also available is Renovo's 430-02-361-0001R Plunger Tube which can be used with your existing jaws after grinding the edges slightly.
