Andersen window spring balance replacements

Question

Hi. I have the following Andersen windows for which I am looking for replacement springs, and have read the part #s off of two of them for reference. Can you tell me which of your part numbers match these?
Thanks,
Ron

Hello,

Based on your stamp codes, the Andersen balances you will need for your windows are:

28 28 28 28 - 24-1033

28 36 28 24 04 L8 12 27 7-87 11600-17 - 24-L8-1227 and 24-R12-827 for the opposite side of the window.

32 24 32 24 E67 9#27 9 8 - 24-939

Thanks for posting!
