I need a constance force window balance for a Simonton double hung non impact window. The coil says 409l. It was installed by a contractor, and bought from Town and Country distributors here in Florida.
The old one is out and I will buy a new one if you tell me how.
Thanks

I believe that your coil spring would be our S170-409. Check it out and let me know what you think!
