Thanks for reaching out! I am confident we have a replacement balance we can supply you with however, to be absolutely sure I'll need to see a photo of an undamaged balance removed from the window.

I am specifically looking to see a photo of the top and bottom plastic attachments from the balance. The stamp provided only indicates the weight range the balance can carry to support the sash. This will be useful once we've determine the type of balance you need.

Let me know if you have any questions in the meantime.
