Incra Miter Slider Miter Bar
This rigid aluminum runner conveniently adjusts from the TOP for perfect sliding action in any standard 3/4" x 3/8" miter gauge slot. Won't warp, shrink, or swell like wooden runners. Adjustment range fits slots measuring 0.740" - 0.760" wide.
A simple turn of a screw adjusts Miter Slider for ZERO sideplay. Another turn locks it securely in place in the miter slot for attaching stationary jigs such as feather boards.
