These beefy mitre slot runners are perfect for the most demanding jig applications!

The heavy steel construction is more rigid than any wooden or plastic runners, and they're not susceptible to changes in humidity or temperature. Mitre Slider SE bars are drilled and tapped with two separate bolt patterns: (4) #10-24 holes attach the bars quickly to your own jigs.  These #10 holes are spaced identically to the original Mitre Slider, so the Mitre Slider SE is a direct, bolt-on upgrade to jigs and fixtures you may have already constructed Mitre Sliders. There's also a second set of (3) 1/4"-20 holes evenly spaced along the length to accept knobs and other fasteners commonly used when building jigs and fixtures.

Long-wearing Nylon GlideLOCK adjusting discs conveniently adjust from the top and provide a precise fit in the mitre slot of most table saws, router tables, and band saws, and the discs also give the bars a smooth, low-friction travel. The 18" bar has two pairs of discs, and the 25.5" bar has three pairs. Both sizes include removable T-slot retaining clips for BOTH ends of the bar for superior stability of larger jigs.
 
Now you can use Incra's patented, perfect fitting mitre bars on your own cross cut jig. Wooden or plastic slides do work, but sometimes they wear quickly or don't offer the support your fixture needs. These heavy steel bars are the best mitre bars on the market and will deliver years of top notch performance.
Each bar is zinc plated to prevent rust, assembled with separate GlideLOCK expansion discs and includes a T-Clip.
