It is thin enough to slide into spring backs, but also has the typical Graflok rails for mounting on any Graflok style back. It can shoot 120 and 220 film, and is pretty simple to load and operate. You don't have to rely on the frame numbers printed on the backing paper to get it into the proper position.
