Andersen sash balance

Question

I need to replace some Andersen Sash Balancers 11600-17 (on a total of five different windows)

I can read the following numbers on the different parts:

Andersen 11600-17 BB6 519 10 67
Andersen 11600-17 D747 #31 12 86
Andersen 11600-17 R13/927 10 87

Can you please help me identifying these parts?

Thank you very much!

Hello! We can definitely help. The key stamps here, I believe, are "519," "7#31," and "927." Are these numbers printed differently on their respective balances, perhaps larger or in a different font? If so, I recommend our 24-531 for the "519," 24-737 for the "7#31," and 24-939 for the "927."
