incra ls positioner only

Now available in imperial or metric!

Now available in both metric and imperial versions, the LS is the beefiest positioner we've ever produced, with rock-solid fence travels of 17", 430mm, 25", 32", or 810mm. Lifting the red locking lever causes the patented steel lead screw positioning system to instantly snap the fence to the dead center of any multiple of 1/32" or 1mm with an accuracy of 0.002" (0.05mm). This allows fence positioning far beyond what's possible by eyesight alone, and fence setups are instantly repeatable. The integrated micro adjust knob allows moving between whole increments with 0.001" (0.025mm) resolution for total control over small fence adjustments.

The lead screw (LS) adds quite a bit of mass, and because it's used for both incremental positioning and the micro adjust, the LS has fewer moving parts than the previous Ultra positioner. Other improvements include recessed, "big view" cursor windows, a large micro adjust knob conveniently located next to the fence, and all of the functions are now controlled by a single lever. And, quite simply, the sleek design is a handsome addition to any modern shop.

The LS17 Fence Positioner is the perfect upgrade for INCRA Router Systems using the earlier Ultra Positioners, and it's also the ideal foundation for any custom system that would benefit from its 1/1000" accuracy and repeatability. In addition to router table applications, the compact size of the LS17 makes it also work well for positioning band saw fences, drill press fences, etc.

The LS25 Fence Positioner is the perfect upgrade for INCRA Router Systems using the earlier Ultra positioners, and it's also the ideal foundation for any custom system that would benefit from its 1/1000” accuracy and repeatability. The mid-sized LS25 allows extra routing capacity on a large router table, and when fitted with the proper sub base, it offers enough fence travel to be used with the INCRA TS Table Saw Rail systems in place of the larger LS32 or Ultra 32 positioners.

INCRA LS 32 Positioner Only
As the largest fence positioner of the LS family, the LS32 was designed specifically for table saw use in conjunction with an INCRA TS Rail System. It's a direct replacement for the Ultra positioners used with the INCRA TS-II and TS-3A Fence Systems, and when equipped with the appropriate sub base, the LS32 can also serve as the foundation of a super-sized, custom router fence system.


The LS17 and LS25 feature a removable, T-slotted sub base under the tubular base housing. The sub base allows super-clean mounting directly to the router table with the fasteners fully concealed. The LS17 is not recommended for use with the INCRA TS Table Saw Rail System.
