Is the metal channel, not including the nylon fittings, 30" in length? If so, see either our S351-30 or S390-30. The difference between these two balances lies in the bottom shoe depth. Compare an undamaged balance to both to see which matches best; if neither seem right, let me know. And let me know if you have any other questions.
