The JET Mobile Base Extension Kit, for the JET JMB-UMB-HD Heavy-Duty Universal Mobile Base (708119), allows you to maneuver your table saw and extension table around your workshop. Now you get the benefits of a larger ripping capacity and a versatile base.
Our mobile base extension kits enable you to mobilize tablesaws that have extended rails and tables up to 60" long. They have the same unique spring pin design as our Universal Mobile Base for quick-snap adjustment. Extension kits come complete with everything you need, including rails. The design allows the machine to be just 1/2" to 5/8" off the floor. Two swivel casters under the legs provide for easy maneuverability. Extension kits can be configured to fit a wide range of tablesaw models for major brands with weights under 1,200 pounds. We recommend using the 708158 with the Powermatic 66 and other brands that weigh over 500 pounds.
