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 29" balance with a 2820 stamp option, meaning your window sash weighs between 12-16 pounds. 

Comparison of the S380 and S385 balance shoes.
