Hello,

We'd be happy to look into this for you but the 17-5 stamp code only indicates the spring strength needed to support the weight of the sash, not the correct replacement. There's a good chance that we can help but we would need to see an undamaged balance assembly removed from your window, including both ends, to compare to our inventory. See the videos we've related on this page to help you through the process. Thank you!

Hi,

Here are some photos of the undamaged balance assembly removed from the window.

Thanks in advance for the help!

Thanks for getting back to us. With this combination of attachments, you could have either the S380-18 or S385-18 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 1750 spring strength options for your replacement balances. Thank you and let us know if you have any other questions or concerns.
