If you're building jigs and fixtures for your table saw, router table, band saw, or other tools with a mitre slot, you need a mitre gauge bar that fits precisely in a standard 3/8" (9.5mm) x 3/4" (19mm) mitre slot and slides smoothly. The Jig and Fixture Bar does both.
This 30" (762mm) long bar has mounting holes every 4" (102mm) along its length that allow you options for mounting your fixtures. Six nylon screws along the length of the bar adjust with the simple turn of a screwdriver to take up any play in the mitre gauge slot. That lets you get an exact fit and retain it over years of use.
