Channel Balance Indentification

Thanks for posting. See the image below. Do both the top and bottom attachments lack 'wings', or side tabs? Please confirm.

If both attachments lack side tabs, you have either our S351-29 or S390-29. The only difference between these two balances is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement, so compare both with your old hardware to see what matches best. See the illustration below for reference. In either case, for a new stamp option go with 2830.
