Channel Balance question - 2820 part number.

A home owner from Tempe, AZ says:

Looks to me like this is either a S351 or an S390.

I am stumped on the foot as it looks like mine measures 1 1/16", but one foot on the above part numbers is 1" and the other is 1 1/8".

There are definitely no wing tabs on either of the top or foot piece.

Can you provide some guidance. Pictures attached.

Hello, Roland. If your shoe is 1-1/16" deep then odds are it was once 1-1/8" and just wore down from years of use. It happens all the time. 1/16" worth of wear is totally normal and it should be okay to use the Series 390 as a replacement.
