U-200P is a bench top frame joining machine and the most popular model with the custom frame shops. It is compact, well constructed, and built for many years of trouble free operation. The design of the U-200P allows the framer to set the front and back stops for V-Nail insertion. The frame is then moved across the nail head and V-Nails are driven or stacked anywhere along the frame joint. The V-Nail insertion is actuated through the use of a pneumatic pedal.
