Hi there..
I have the "standard fence assembly" fence and rails that originally came with my Sawstop. SawStop | We are the contractor Table Saw of choice | SawStop

Not the Biesemeyer Style but I believe these work just fine... I don't use it as I already had a Biesemeyer Style fence from my previous saw...
