Includes QTY3 stiffener rails for your standard Shapeoko 3 router. These are strongly recommended alongside our Shapeoko 3 fixture plates and increase your machine's rigidity.
Stiffener Rails are compatible with Shapeoko 3 and 3 XL machines with SMW Fixture Plates. Threaded inserts on the Shapeoko 3 XL's factory rails must be drilled out to accommodate mounting screws. Shapeoko 3 XL plates ordered before 02/01/2021 are not compatible with SMW Stiffener Rails and we recommend using 80/20 extrusion instead (1030 size).
Stiffener rails can be used on the Shapeoko 3 and 3 XL without an SMW Shapeoko 3 Fixture Plate, but require modification to the machine's spoilboard. We recommend use with our fixture plate for maximum compatibility. Download this STEP file for stiffener rail hole mounting locations with the standard Shapeoko 3 spoilboard.
NOTE: This product is not compatible with Shapeoko 3 XXL routers, which have stiffener rails built into the machine frame.
