Trying to find this part. It is an old window. Look that different conversations on the website but not really helpful. The balancer is very old in the markings are hard to see.
This is an old Andersen Window. The balancer is gone. Can't find a replacement because the markings are very difficult to see. From end-to-end including the tab is 6 1/2 in by 3 in. It is a double paned window.l have read some of the forums and people seem to be submitting a 3 digit number that is located on the tab. I have no such number. I do not see a three digit number anywhere on the balance balance.
