I know this is an old post, but I have this unit and use it with all my SU ribbon. The 1/4 grosgrain spools sit up a little higher, they do not fit "inside", (all the rest sit completely inside of the holder), but they are secure and I am able to pull out the ribbon without problems. If you are still interested, PM me and I can send you a pic of what it looks like.
