    Lead Screw (LS) Technology

    The LS stands for Lead Screw. INCRA's patented Lead Screw technology makes this unit the leader in precision positioners for woodworking.

    The LS positioner's accuracy is +/- 0.05mm - the lead screw's 1mm 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 1/20mm steps to tweak the width of a groove or zero the fence against a router bit.

    The fence used for the Standard Systems is the 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.

    INCRA Wonder Fence 

    The Wonder Fence slides into the front T-slot of the Pro-II joinery fence, and it adds adjustability to accept any size router bit and accommodates zero-clearance subfences. The Wonder Fence also adds the ability to very precisely offset the infeed and outfeed fence halves for edge jointing rough timber or setting up for complex moulding jobs like reversible glue joints. 

    The LS Super Systems are available with either 17" or 430mm travel LS units to provide their positioning accuracy. INCRA's patented lead screw positioning mechanism allows any woodworker to quickly set the fence within 1/1,000" (0.025mm) of any desired position. In woodworking terms, that's accurate enough to split the line from a sharp pencil into 25 equal parts! And because an INCRA positioner is mechanical in nature, every fence setup is easily repeatable with zero error, hours or weeks later.

    INCRA Master Reference Guide & Template Library.

    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

    INCRA's 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 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 Instructional DVD

    The LS systems are topped off with a 82 minute instructional DVD - this great disc is loaded with information - how to take advantage of the optional Wonder Fence's advanced features, cut perfect fitting rabbets and dadoes, and it has full-length instructions for box joints and the four most common styles of dovetail joints.

      Super accurate, very well made, sturdy, top quality. On the other hand... it is very expensive and it is beyond huge, hence the 2 stars missing. You have to be a serious woodworker with a good amount of money and a lot of space spare in order to install the LS system to be ready to use as needed or, like me, you will have to install it in a way that you can move it or rotate it when you are not using it, as the back of the LS system (opposite the fence) needs depending on the length you buy, all that extra space for the LS arm to extrude beyond the table. But, if I had lots of money and lots of space it would have 5 stars from me

      Accurate fence

      The Incra fence allows accurate and repeatable fence positioning on either a router or table saw. I added wooden extensions to my router and saw tables. Excellent for accurate dimensioning, trenching and joint cutting
