Purchesed the edge guide with the Dewalt 611PK router.  Fits up to the plunge base only.  Will not fit up to the fixed base.  The fixed base has its own model edge guide.  However, this unit has all the bells and whistles of a high end edge guide. In addition, it will fit up to all Dewalt routers.

Review after (3) months of use.
Holds its setting very well, no issues here.  The long edge guide is very helpful and a must when doing cabinet work.  The edge guide is low profile when the vacuum port is removed.  However, chip build-up around the base becomes a problem.  I highly recommend this attachment.
