22.5 pound window Balancer

Thanks for reaching out to us. I agree that  the S385-19 is the right balance, but the 1850 stamp would be too weak for your sash weight. Please give us a little time to see what we can do about that and I'll get back to you ASAP.

In the meantime, can you tell me what your old stamp reads?

Thanks! That's definitely a match for our 1850 stamp option, but two balances with an 1850 only carry 17 through 20 pounds. I still think that would be too weak for your 22.5 pound sash.

It's ultimately up to you. You can stick with the 1850 stamp, which might be a little too weak. However, we just added the 1860 stamp option for you on the S385-19 store page. Two balances with this stamp can carry 20 through 23 pounds, which should be better suited for your sash weight. That would be my recommendation.
