Hi, I have a Window Balance that has stamped on it "2740: BSI LF
Can you help identify the proper replacement and how much it costs?
I live in California.

Thanks

For us to properly identify a channel balance, we would need to see some photos of the entire balance. In addition, you need to provide the metal length measurement of the balance, as well as the channel width. From there we can search for a replacement.
