I put a replacement spiral balance (900 Series) in and it seemed to work fine. It raised properly, but when I closed the window the balance broke.
I tried it a second time and the same thing happened. The 29" balance (metal tube length) is the same as the original. The 3/8" is also the same. I charged the balance four times the first try, and two times on the second try. I watched your video on tilt window spiral balance replacements.
Help, I have ten more of these windows to service!
