I just wanted to pop in and say that this question has been asked before. I can't search right now because I am running out the door to do some work. If I remember correctly it will be close to being able to accept that bit if all the mounting rings have been removed. The CMS here is the same as in other countries with the exception of the switch and electrical components and sets are offered here only versus being able to buy individual parts outside of North America.
I don't think that it is a secret that there are CMS set up in North America with 2200's residing below the insert, but as a moderator I am supposed to cut and paste the following statement just to make sure that the risks are known:
"Warning: The Festool CMS System is approved for use with only the OF 1400 and OF 1010 routers in the US and Canadian markets. It is not approved for use with the OF 2200, nor with any of the CMS modules currently available outside the US and Canadian markets (TS, Jigsaw and sanding modules). Festool USA does not endorse the use of these components and will not support them with spare parts or repairs. The use of anything other than the OF 1400 and OF 1010 routers and their related accessories with the CMS will void the warranty agreement on the entire system for customers within the US and Canada. Festool does not endorse the application or use of any Festool product in any way other than in the manner described in the Festool Instruction Manual. To reduce the risk of serious injury and/or damage to your Festool product, always read, understand and follow all warnings and instructions in your Festool product's Instruction Manual."
If you don'g get an answer from a member, try doing a search for "opening size" and in the by area type in Tom Bellamare.
