I'm looking for a 1" OD router template guide for a OF 1400 EQ and the only Festool one I can find is the 495341. The specs for this list it as a being for the 2200. Will it fit the 1400??
No it won't. You could use the 493566 guide bushing adaptor and then a standard (Porter Cable style) threaded 1" bushing. I have the adaptor but don't remember buying it. You might already have one, but the scope of delivery for some products has changed since I bought my 1400.
