The Miter-Gauge Bar fits precisely in a standard 9 mm x 19 mm miter slot and allows you to build jigs and fixtures for your table saw, router table, band saw, or other tools with a miter slot. This is the same adjustable bar that comes standard on Kreg Precision Miter Gauge, giving you the same proven accuracy on fixtures you build. Six nylon screws along the length of the bar adjust with the simple turn of a screwdriver to take up any play in the miter gauge slot and make it slide smoothly. This 762 mm long bar has mounting holes every 102 mm along its length that allow you options for mounting your fixtures.
