The bottom sashes (the only sashes I'm working on as the upper sashes are painted shut and won't be used anyway) are 9.4 lbs.
The tube is 28" long and the diameter is 5/8".
Thanks so much!

Thanks for posting. See our S500-28 Spiral Balance. The Series 500 is often a good option to replace spiral balances in old, non-tilt windows. For the color tip, go with the red option, which will work for a window in the weight range of 7 through 29 pounds. Let me know if you have further questions.

I need to get new brackets as well and I'm having difficulty determining which ones to order. Here are photos with the measurements. Thank you!

I believe is the 70-010 Bracket, often used with Series 400 and Series 500 Spiral Balances. Please compare.
