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.

You will need a 19" length with a 1830 stamp option that can support a 12 to 14 lb window sash. Please review and let us know if you have any additional questions!
