Bosch Colt PR111 plunge router base faceplate with holes for the Bosch quick change template guide adapter

Bosch routers use a quick change adapter RA1129, that allows quickly moving to either the standard Bosch guides or the circular brass ones . This modification allows that adapter to be screwed on to the plunge faceplate of the Colt so that it can then quickly change standard Bosch guides. The RA1129 also has an adapter that allows use of the brass screw on guides.
