Replacement Balance ID

Thanks for posting. Please double-check the metal channel length. Be sure not to include the nylon fittings on either end in the measurement. I believe it should come out to 21". If so, you likely have either an S351-21 or S390-21. The only difference between these two balances is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement. See the diagram below for reference. Compare both balances with your old hardware to determine what you need. In either case, for a stamp option choose 2030.
