A quick learner from new jersey says:
I have two windows that need replacement of sash balance. The part images were uploaded. The number shows D20 7 #27 1034.Can you please let me know which parts I should buy for the job. Do you sell them in pairs or I should order individually? Thanks

Take a look at our 24-737. This can replace Andersen balance boxes stamped with 7#27. These are sold individually.
