Your stamps are actually a little weird. Can you give me the height and width of the visible glass for the sash these balances support?

Thanks for your patience. We should be able to help, but we need a bit more time for them to be made up for you. Please bear with us and I'll let you know when these parts become available for you to review.

Hello, For your Andersen Narroline sash balances, we came up with these replacements:
28.5 wide X 20 high visible glass = 24-737
36.5 X 20 = 24-837
40.5 X 33 = 24-16L (left) and 24-16R (right)
