Spacers are used on cranks where the spider arms are drilled and tapped for inner chainring mounting but standoffs are not forged into the arms themselves. Older Sugino triple cranks such as the AT and GT are examples of such cranks. They are also used on "tripleized" cranks where the inner chainring mounts to a second set of holes on the middle chainring rather than directly to the crank.
