I think it's 1 1/8. (More like 1 1/16)
another couple are stamped with 33 4 FO CALDWELL

Hi Tom,
I have three more questions:
A couple of my windows (I have ten of the same window) slide up easily, stay up fine, but require a lot of effort to close... do you have any idea what is causing this problem and I need to do about it...
Another window opens and closes, but makes a scraping noise on one side... what is the cause and remedy for this prole?
How do I decide what weight to get? do I need to weigh the window sash?
thanks,
David
Thanks for getting back to us, David. For the window that can't close easily, it's possible that you don't have the appropriate strength spring. What is the weight of the sash, and what is the stamp printed on the metal channel?
As for the window that scrapes, I'm not sure what that could be. It may just be the age of the balance showing. Is it something recent, or has it always been noisy?
To determine the weight of your sash, you will have to weigh it.
