Window balance

A handy person from Naperville, IL says:
Need to replace several window balances. I took one out and it looks similar to those on your website. The numbers I see on the part are:

E47 8 #47. 10-86


Can you tell me the part I need?

Thanks. Tom.

Thank you for contacting us. We are having trouble finding a match for this balance. Can I see a few pictures of the stamps in question? Specifically, I would like to see a clear picture of the stamp that reads 8#47. Thank you!

Thanks for your help. Look forward to hearing back from you. These windows were installed new in 1987.

Ah, thank you. Looks like the stamp reads 8#37, not 8#47. I recommend you look at our 24-837, which can replace Andersen balance boxes with this stamp.
