27 3 Balances

Hello,

With this combination of attachments, you could have either the S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. I'd recommend double-checking the length of the balance channel, not including the end fittings, since your stamp would generally indicate that your balances would measure 28" long. 

You'll also need 2730 spring strength options for your replacement balances. Thank you and let us know if you have any other questions or concerns.
