Thanks for posting, Duke. Can you confirm the diameter of the balance tube? It should be either 3/8" or 5/8" (it may also be 9/16", though it's considered 5/8" in the trade). Please double check and let me know!

Can you also tell me the weight of your window sash?

The diameter is very close to 1/2 inch, really 7/16th. So the closest option is 3/8.
The sash weight is 9.3 pounds
Thanks for your clarifying questions

Thanks, Duke! I think you might want to consider our S500-26 spiral balance with a 17-012 bracket. This kind of set up has been the standard for wood windows for 75 years. Check it out and let me know what you think.
