Incra's Flip Shop Stop offers instant, repeatable accuracy for less downtime and more productivity. Dual, pivoting flip arms mean dead on accuracy. The machine bar is fitted with Incra's exclusive top-mounted, T-slot retainer clip, which is easily removed for use in non-T-slot channels. Four expansion points adjust for zero side play, anti-friction travel on all tools with standard miter gauge channels, including Delta, Craftsman, and imports. This means the bar won't wiggle around in the miter slot. Also, with the Universal Mounting Bracket that supports any user-made fence as well as any Incra fence, it's possible to put an Incra Miter Gauge in every standard miter channel in your shop.
