I purchased this insert to attached my 3 1/2 hp Milwaukee router for table use.  I spoke directly with the manufacturer with my request for a template to accommodate my router.  I spoke with three people and finally an engineer I spoke with simply stated they did not provide one for my router.  No offer of any kind of assistance.  I had to approximate the layout, using the Milwaukee stock base plate as a guide.  This task is more difficult than you may assume, depth of recess and spacing of the 3 screw holes needs to be exact.  My effort is pretty close, since I had a business associate drill and counter bore the three holes for me at his prototype Lab. Even so, a Rousseau provided template would have been more accurate than using the base plate turned out to be.  I would think that providing one would be very easy for them to produce - even send to a client as an email attachment, with a depth and drill size recommendation.  No customer service focus at Rousseau that I could find.
