Dress up your mitered corner joints and add strength, too, with the Rockler Router Table Spline Jig. This clever jig locks into a standard router table miter slot and features a sled that holds your workpiece at a 45° angle while you guide it smoothly past the router bit. The adjustable fences act as stops to position your workpiece—one setting can cut all four slots for a frame, or eight slots for a box. Try different router bits to achieve different effects—straight bits, V-groove bits, dovetail bits and more. For larger boxes, this package also includes the Large Box Spline Jig, which is clamped directly to your project.

  • Smooth-sliding tracks ensure accurate cuts and ease of use
  • Includes centering tool, which aligns the jig with the center of the router bit; stores onboard
  • Taller fences can be added to stock fences to stabilize larger frames
  • All adjustments are achieved with tool-free knobs
  • Fits router tables on which center of miter track is between 3-1/4'' and 6-7/8'' from center of the bit

Package also includes Large Box Spline Jig for adding strength and decoration to large projects!

Cutting decorative splines for large boxes that can't be machined on the router table is easy with the Rockler Large Box Spline Jig. This jig clamps to the outside corner of your box or chest to provide a precise 45° sliding surface for your router. The jig's fence is adjustable so you can align the cut line with the center of your particular router. Once set, operation is simple. Just position the jig, clamp and rout. For very large boxes, space is provided for clamping cauls that can span the width of the workpiece. Try different router bits—straight bits, V-groove bits, dovetail bits and more—to achieve different effects.

  • Adjustable fence aligns the jig with your particular router's base
  • Corner relief protects delicate corners and ensures a tight fit to the workpiece
  • Large clamping areas can accommodate cauls for the biggest boxes
  • Made of durable ABS plastic with engineered structural strength
