Sash balance

Thanks for posting. I am confident we can help replace this channel balance, but that stamp actually is not an identifier--it just indicates the balance strength. Can you show us the other nylon attachment while the balance is out of the window? We need to see both to properly narrow down what it could be. Many thanks.

It is, thanks. This looks like an S395-29 Channel Balance. For a stamp option choose 2830. Let me know if you have further questions.
