Which Anderson Windows Sash balance

A quick learner from Berlin, NJ says:
Hall Bath: Double Hung Pane 32 1/4 X 16
Master Bath: Double Hung Pane 24 1/4 X 20

Please tell me what sash balances that I should order to repair these two windows.
The stampings on the ledges of the parts are shown in photo. There is an additional stamping that says 11600-17.
These windows were installed in 1990.
Thank you for your help. Sorry that your parts counter in Camden closed.

Thanks for posting, Gerald. Thank you for your well wishes.

For the master bath, I think that stamp might read 8 23 instead of B 23. If you agree, I recommend our 24-837 , which can replace boxes stamped with the number 8 23.

For the hall bath, check out our 24-737 , which can replace Andersen balance boxes with the stamp, 7 25.
