All my sash windows are broken and I need replacement channel balances. My windows don't have a manufacturer on them (this is a tract home) so I took a bunch of pictures of the balance. I just want to make sure I order the right thing! Can you help me get the right part number?

Hello, Patrick. I think I can help, yes. See our S385-31 to start with and let me know how well this matches your hardware.
