I believe I need series 385. Please confirm. The window weight is 15.4 pounds. The metal length is 28 inches.

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.
You'll also need 2730 spring strength options for your replacement balances, which will support a sash between 13-19 lbs. Thank you and let us know if you have any other questions or concerns.
