With this combination of attachments, you could have either an S380-30 or S385-30 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 2965 spring strength options since your balance stamp indicates that the window sash weighs 38 pounds. Feel free to weigh your sash to confirm that this is correct. 

Thank you and let us know if you have any other questions or concerns.
