balance parts

Thank you for reaching out to us. We should be able to assist with this. However, the bottom shoe is too broken. May we see a photo of an undamaged version removed from the window? Can you also show us a photo of the inside of the metal channel where the inner spring connects to the pulley mechanism?

Thank you very much! Based on what I see here, you can use the S380-26 or S385-26 channel balances. The best match will depend on the bottom shoe depth as shown below. You'll also want to select the 2550 stamp option based on your old stamp.

I'll be here if you have any questions!
