Attached is the channel balance part that I need replaced. 10 in metal tube, with each end indicated. The stamped number is 1530 , with some other letters next to it that look like B.S.I. Hopefully you can identify it. I would need a new pair for my window. Thanks

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.
My concern is the length of the metal channel excluding the attachments. Are you able to double check this measurement? With a 1530 stamp, the metal channel should measure 16", not 10". Please let me know!
