I need S351-19 Channel Balance. I don't know what option I need. The stamping on the balance I have reads "28 3 JO CALDWELL". Can you tell me what option I need? Thanks

Thanks for posting! Can you please confirm the length of your channel balance? With a length of only 19", I would think that the stamp would read something more along the lines of "18 3 JO CALDWELL." Please let me know!

My mistake. It is 29" and should be S351-29.

Oh, I see. Thank you for the clarification. In that case, a balance with the stamp of "28 3" will want the 2830 stamp option.
