Need to replace 2 channel balances

Hello, thank you for posting,

With this combination of attachments, you could have either an 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. 

To move forward, are you able to confirm the length of the metal channel excluding the nylon attachments? Thank you!
