Well, I only got mine in the post 15 hours ago, but I would say 'not without some modification'! The back snugly fits a standard double dark slide holder, but doesn't have the width for a grafmatic, or the graflok sliders for a roll film holder. You might be pushing it to even get one of those old Calumet or adapt-a-roll roll film holders in either (although having now said that, that's the first thing I'll test when I get home later on)...

Marc!
