Help!!!!

Hello, thank you for posting,

With this combination of attachments, you could have either an S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You will need a 30" balance with a 2920 stamp option. 

Please review and let us know if you have any additional questions.

If the depth of your shoe is neither of the below and is actually 7/8", please let me know!
