The heavy steel construction is more rigid than any wooden or plastic runners, and they're not susceptible to changes in humidity or temperature. Miter Slider SE bars are drilled and tapped with two separate bolt patterns: (4) #10-24 holes attach the bars quickly to your own custom jigs and they also match perfectly with the INCRA Build-It Panels. These #10 holes are spaced identically to the original Miter Slider, so the Miter Slider SE is a direct, bolt-on upgrade to jigs and fixtures you may have already constructed Miter 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 fixture.
Long-wearing Nylon GlideLOCK adjusting discs conveniently adjust from the top and provide a precise fit in the miter 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.
Compatibility: The Miter Slider SE will fit square-sided miter slots approximately 3/4" wide, 3/8" deep, and with or without a 15/16"-wide T-slot at the bottom. The GlideLOCK adjustment will accommodate slots measuring 0.740" to 0.765" in actual width.
The Miter Slider SE is not recommended for stationary jigs that must be locked into position within a miter slot. The standard aluminum Miter Slider is the best choice for these applications
