Jessem Precision Box Joint Jig

JessEm Box Joint Jig: Perfect-Fitting Finger Joints, Every Single Pass

Achieve flawless box joints with confidence. The JessEm Box Joint Jig turns your router table into a precision joinery station, giving you tight, perfectly fitting finger joints with minimal setup and repeatable accuracy. It is built for woodworkers who want clean, professional results without the fuss, so you can move from drawers to keepsake boxes and cabinetry knowing each joint will fit exactly as it should.

At the heart of the jig are four precision R4 bearings that glide smoothly across your router table for clean, consistent cuts every time. Three precision-machined aluminium indexing keys and three matching Baltic birch fences let you switch between the most popular joint sizes in moments, with no complicated adjustments. Its innovative design also keeps your router lift fully accessible, so you can tweak bit height or lock your lift without ever removing the jig or router plate.
