Spring lift assembly for Atrium DH window

Quick Learner from Chaplin, CT
I am looking for the side bar assembly that includes the steel chase, spring and string with pulleys. I am looking for 4 of these assemblies. As you can see in the last 2 pics, the chase is compromised as it bent when I was trying to reassemble the spring

Hello! I think we can help with this balance, but the balance you've removed is unfortunately too damaged for me to ID. I think we can help, but before I narrow down the list of possibilities I'd like you to remove an undamaged version and show me a clear, close up photo of the top end, bottom end, stamp, and the hook or shoe at the end of the cord. Thanks!

I did not want to rake it all apart again until I repair it. I took closer pictures of parts you inquired about with a ruler to show size and a micrometer for the thickness of the steel chase

These photos are a huge help, thank you! Based on what I see here, I feel confident that our Series 770 tilt window channel balance is what you want. This has the same square "terminal clip" at the end of the cord as yours, which is a distinct part that, to my knowledge, is only used on this Series. Give it a look and let me know if you had any questions.
