Spiral balancer

Question

Hi...

Does the tip color on a spiral balance indicate what weight sash it will carry? I will be retrofitting spiral balances in a large double hung that had channel balances originally but the s-hook bends easily under the weight of the sash. We are current Swisco customers, Bohemia Glass and Window. These sash are 35" x 36" and probably weigh 50 pounds.

Thanks.

Yes, that's correct. We have a chart on the S600-35 store page that tells you exactly how much weight each option can support. However, 50 pounds is exceptionally heavy. I'm not sure if we can make a version of this balance that can support that kind of weight. Can you confirm exactly how heavy the sash is? The S600-35 may not work for you.
