Our Standard LS17 Systems match either a 17" or 430mm travel LS positioner with the best INCRA accessories for joinery, and the possibilities nearly endless. The Standard Systems can take you from basics like flawless rabbets, friction-fit dadoes, and repetitive slotting jobs to literally billions of variations of box joints and dovetail joints ranging from traditional to absolutely stunning.



Have you ever wondered what makes our systems work? An INCRA Jig is a mechanical fence positioner - its job is to allow any woodworker, regardless of experience, to quickly make a fence setup on a router table within 1/1,000" (0.025mm) of a 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 hours or weeks later.





The positioning mechanics are as simple as the concept: An LS positioner has only four moving parts. A steel lead screw housed in the sliding carriage threads on 1/32" or 1mm spacing, and a matching set of threads is driven by the large clamping lever. As the lever is raised, the threads mesh, forcing the fence to index, or "center-up" on only perfect multiples of 1/32" or 1mm with no way for you to miss.
