This stainless steel rack holds up to 12 sheet of 2x3 sheet film and fits in most stainless steel roll film tanks (make sure your's is tall enough to accept 3.25 film). They originally came with some sort of loading guide. Since it's missing from this one I doubt that you could reliably load all 12 sheets, so I would assume 6.
