I agree. You have to have holes for guide rods in the router for the CRB7 to work.
M Power offers 4 sizes of rods. The spacing between the rods and the height of the rods is adjustable(the smaller 2 sizes of rods come with the CRB7) so any router that has the guide rod holes, no matter what the size or spacing, can be used with the CRB7. A router that does not have the guide rod holes cannot be used with the CRB7, unless you build a thick base for the router and drill holes through it for the guide rods. Locking screws to lock the router position to the rods would also be necessary. It's doable, but much easier to just use a different router.
