The 120 back is the most common film back available, and one of the few remaining useful backs for modern ETR System users. As 220 film is no longer produced, these backs are no longer of great use. It is also possible to load 120 film in a 220 film back. Note that 120 inserts can be put inside 220 frames, and visa versa.
