Windows balance 25"

Thanks for reaching out to us! Your window balance reminds me of the Series 770 Balance. Since the length of your channel is 25", you'll need the S770-25.

The stamp from your channel does not cross-reference with the stamps on our replacements. That said, I'll need to know the weight of your sash to determine the correct one. 

Please also confirm whether your balances screw in or hook in at the top of the window track.

Feel free to reach out with any questions!
