Channel Balance part number

Thanks for posting. I am confident we can help, but I need just a little more information. Could you show us closer photos of both attachments on the ends? Can you also show us any stamp on the metal channel? We should be able to narrow this down from there. 

Thanks for these new photos. Based on what I see here, you have either our Series 351 or Series 390, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.

Comparison of the S351 and S390 balance shoes.

Great! Thanks for the order and please feel free to reach out if we can be of any further assistance.
