If your tank is wide enough to accomodate 120 film then the reel should adjust to the 120 width. If your tank is dedicated to 35mm, then I suggest a Paterson tank (and if you have trouble loading the Paterson reels, get an Ultra Reel (with wide flanges) to use in the Paterson tank.
Don't get discouraged. THe Ultra reels are a god-send for loading 120 sized film.
