Hello,
I am trying to get replacements for my window. I'm pretty sure that I need series 385, but I don't know what the weight is. There is a stamp that states 27 5 BSI OB.
Do you know which model I need?
Thank you!

Hello, thank you for posting,
Based on the stamp, you would need a 2750 stamp option that can support a 26 to 30 lb window sash. Please review and let us know if you have any additional questions!
