david, The length of the chain on the American Standard M962749-0070A can easily be adjusted. The ball at one end can be removed from its slot, and then the chain moved and a different spot can be inserted into the same slot. Your American Standard Consumer Connection Team.
Kenguil, unfortunately this is not designed for the Champion models. The chain is part of the flush valve and that would need to be ordered. Sincerely, your American Standard Consumer Connection Team
