replacement sash balance

Thanks for writing in! I am confident that we can supply you with a replacement however, the number provided does not provide enough information to identify the proper replacement. It is possible that there may be other stamps on the balance that may help to determine the correct replacement. 

You may need to remove them the balance to expose those stamps.

Please let me know if you have any questions.

Thanks for confirming this information. You'll need the 24-837 Andersen Sash Balance. This is used for balances stamped with an 823, 827, 831, and 837.
