3330 Channel Balance

Thanks for reaching out. I am unable to identify the balances you need based on the stamp alone. The stamp only indicates the weight range your balances should be able to carry. 

To identify the proper series balance for your window, I'll need to see a photo of an undamaged balance completely removed from the window. I've include two video below that detail how to remove the balances and the information we'll need to identify the proper replacements. Let me know if you have any questions.
