Please help identify the Channel Balance to replace

Thanks for posting! 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'll need to see photos of the bot the top and bottom plastic attachments from the balance, from a side profile view. 

The stamp provided only indicates the weight range the balance can carry to support the sash. Unfortunately, it cannot be used to identify the Balances series needed to make your repairs.

Please let me know if you have any questions in the meantime.
