Jon, the 26620 router is different from a Bosch 1617 in the design of it's sub base plate. It will not use Bosch style guide bushings (or PC style for that matter) and is only designed to work with the Craftsman plastic guide bushings which are of poor quality. The edge guide should fit, simply measure the hole size in the side of your routers base and compare it to a 1617. Since most routers end up being fitted with aftermarket sub base plates or mounting plates for table use this is not a big deal. An excellent value for your money. Sadly this model has been discontinued.
