I'm looking for the appropriate balances for two seperate Andersen double hung sash windows.
First window balance had the markings: S271031. 11600-17
Second window balance had the markings: S141027 5-88. 11600-17

Thanks for posting. Without photos of the stamps I can't be 100% certain, but I think the 24-1033 will work to replace both sets of window balances. The 24-1033 will replace old Andersen balances with the stamps 1027 and 1033. Let me know if you have further questions.
