Coil Balance

Thanks for reaching out! The part you have pictured here is the open cam T-Lock Balance shoe, which is typically attached to the Series 795 Channel Balance. The replacement for this shoe would be our 15-195B. 

Dimensions for 15-195B

Given that your shoe is broken, it might be likely that you'll need to replace the channel balance. In the event that you do, you'll need to confirm the length of the metal channel as well as the stamp from the metal channel. Also, if your your metal channel has a hook connected to the top, please let me know.
