Here's a new product that combines the versatility of the INCRA Build-It products with the unique performance and feel of the adjustable GlideLOCK miter bar used on INCRA Miter Gauges.   The steel bars are 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 with two separate bolt patterns:  (4) #10-24 holes match perfectly with the INCRA Build-It Panels, and there's 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 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 is compatible with all INCRA Build-It Panels, and will fit square-sided miter slots approximately 3/4” wide x 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.
