Hello, needed to order new window balances for most of my windows. Want to make sure I'm ordering the correct size. Thank you.

Hello, thank you for posting,

With this combination of attachments, you could have either an S380 or S385 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.

The length of the metal channel excluding the nylon attachments should measure 30" long and you will need a 2930 stamp option. Please review and let me know if you have any additional questions.

Comparison of the S378, S380 and S385 balance shoes.

Just measured, it's a 380 series. Do you know what sash guide I would need, or do I have to measure one of them too?
Thank you so much.

There are many different top sash guide options. To further review, we would need to see a picture of an undamaged original. Either removed from the window or where we can see the front of it on the side of the window sash. Thank you!

Please start by reviewing the style and dimensions of the 18-166, 18-064 or 18-009 top sash guides to see how they compare for a good fit. Let me know what you think!
