Good morning I need to replace my Anderson window balances in one my windows from 2003. Based on the photos and the following numbers:

11600-17
11L U73

Can you recommend what replacement balance I should order. Thank you.

Hello,

The 11L stamp on your balance housing indicates that you would need the 24-11L Andersen sash balance. See the 24-11R for the opposite-handed version of this balance assembly. Thanks for posting!
