What is the correct option for my balance?

A home owner from Tigard, OR says:
I have a balance stamped "25 4 GO CALDWELL" The S385-26 appears to be the correct balance to replace this but I'm not sure about the weight option.

Due to the "25 4" I would think the 2540 would be the right option, but when I weighed the sash it was 17 pounds, which makes me think the 2530 would be correct.

Would you recommend I go with the 2540 to be as similar as possible to the old balance or go with the 2530 as that is correct for the sash weight?

Thank you for posting! Yes, usually a stamp of 25 4 would correspond to our 2540 option, but I would base your decision off of what the sash weighs rather than what is stamped on your balances. It's possible that whoever installed these to begin with was mistaken. Did you ever find your windows to be difficult top open or close?
A home owner from Tigard, OR says:
Opening never seemed much of a problem but closing them always seemed to require a fair bit of effort to get them pushed all the way down. I suppose that makes sense if the balance was designed for a heavier sash that would mean I needed to provide extra effort to make up for the lighter weight of the sash. Thank you for you help.

Yeah, that makes perfect sense. The 2530 is probably a better choice.

I was happy to help! If you have any other questions, please don't hesitate to ask.
