INCRA LS Positioner Super System
(17" shown here with optional INCRA Router Table)

Now available in imperial or metric!

The world's most versatile and accurate movable fence for your router table, drill press, or band saw, gets even more useful in this system which includes the leading split fence design, the Wonder Fence. Designed to meet the needs of the most serious woodworker yet easy enough for even a beginner to use. The INCRA LS Super System has all of the precision and versatility of our other tools, plus a host of new features and design details that set it apart from anything else.

This sytem is the ultimate in precision fence systems for serious joinery and woodworking fans.The LS stands for Lead Screw. Our patented Lead Screw technology (U.S. Patent #5,716,045) makes this unit the leader in precision positioners for woodworking.
Available in 17", 25" and the NEW 430mm & 635mm Metric Editions. INCRA LS Metric Conversion Kits are also available.
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.

The 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 lumber 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.
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 Instructional DVD - 82 Minutes
The LS systems are topped off with a 1hr, 22min 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.

In hands on tests against five competitors, the INCRA LS Positioner Super System came out on top with all positive comments, no negatives at all! As a result, it was chosen as the single Editor's Choice among all of the well-known fence positioning systems.

If you are new to woodworking, the Incra system reviewed here is primarily designed as a router table jig. Incra also makes a similar system that can be used as a tablesaw rip fence that can also accept the Wonder Fence for router operations. The positioner can and has been used for a multitude of applications besides these though.

If you have never used one of these incremental jigs before, you are in for a treat. It will only take about five minutes of operation to conclude they are the best thing since the invention of the circular saw blade. The Incra LS Super System represents one of the major milestones in modern oodworking accessories. Incra could justifiably alter the ad line from Dupont and say "We don't cut the wood, we allow it to be cut accurately".
