The OFA router adaptor base is part of the Bosch FSN guide rail system. Attach the router so that it can then be guided by the guide rail. This base can be attached to almost any router. Please note, there are a range of pre-drilled holes in the base; further holes can be drilled if required.

Good bit of kitBought this to get me out of a hole, which it did, useful to know that this runs on Makita track as well as Bosch.

OK but build quality could be betterBought this to fit my Bosch GOF 1300. Instructions say it is compatible using pre drilled holes. Also the base plate tells you which holes to use, but the existing drillings were way off, no matter which ones I tried, so I had to drill new locations. Also the backlash on the lateral adjustment is approx 0.75mm, giving a large amount of play, which, when trying to route tight dados using the guide rail is not helpful. After several practice runs I did manage to get some accuracy, then would you believe it - my router burnt out. Big bang, smoke, blown fuse. Now in the market for a replacement router!
