Channel balance

Hey there! The balances you have are likely either the S380-33 or the S385-33 with a 3240 stamp. To determine which of these is the series you'll need, confirm the dimension for the depth of the bottom shoe. It should either be 1" or 1-3/32". Let me know if it doesn't match either measurement.
