Mortise Centering Router Base
Perform easy mortises with the router without the fear of keeping the guides firmly against the work. The adjustable guide block slides around a semi-circular slot making contact with the project. Here it locks in position to keep the router in full control.
The clear acrylic base allows full view of the work. An insert specifically used for marking and positioning the base is supplied. Guide pins are adjustable for material thicknesses up to 4-3/4".
Predrilled hole pattern fits: Makita RF1100-1101 series or similar, Bosch 1617-1618 series, Porter Cable 690/890 series and Dewalt DW616/DW618.
