Sorry to hear about the problem. It definitely sounds like the balances are too short, even after you moved it down. That said, moving the installation hole down an inch should have made up for it. What is the exact length of the tube for the old balance? Can you also tell me the exact length of the inside spiral?

Thank you. If those measurements came up short when you closed the sash, then I would recommend our S900-27. This has a 27" long tube an a 28" long spiral.
