The Lead Screw (LS) Technology
The LS positioner's accuracy is +/- .002" on the lead screw's 1/32" increments across its entire range, so it's essentially perfect even without the built-in micro adjust. The large micro-adjust knob turns the lead screw against the mating threads, allowing the fence to be shifted in .001" steps to tweak the width of a groove or zero the fence against a router bit. The fence used for the Standard Systems is our Pro-II 28" fence, which features a surface that's machined flat in a milling machine and a T-slot for adding fixtures or adding the Incra Wonder Fence in the future. The Pro-II fence directly accepts the Shop Stop or INCRA Stop, and there's also a telescoping extender bar for stopping grooves being cut into longer boards.

This LS Fence system also includes:
The INCRA Master Reference Guide & Template Library. The Master Reference Guide provides straightforward instructions and 51 joinery templates (25 templates in the metric version) to slide into the positioner to provide a visual reference for each joint pattern.
Those templates can produce a mind-boggling variety of joints - 11 box joint patterns and 29 dovetail patterns are included (or 9 metric box joints and 16 metric dovetails), and each one of the dovetail patterns can be cut half blind, through, sliding, or corner post.
INCRA Jumbo Right Angle Fixture &
INCRA Shop Stop
Our largest Right Angle Fixture is included to keep workpieces square to the fence and square to the table for joinery operations. Instead of the basic stop block of typical router fences, the included INCRA Shop Stop is based on our patented incremental positioning racks to give you unparalleled accuracy and repeatability when limiting a board's travel across the router bit or setting the endpoints of stopped grooves for drawer and box bottoms.
INCRA LS Online Instructional Video

The Auto- Centering Scale (imperial systems only) fits in a third channel to Automatically and Effortlessly center your work for any operation.
