Good Morning,
When the string or the nylon attachments break on a channel balance, that is usually a sign that the balance needs to be replaced. The stamp you provided only tells us the spring length and strength. If you are sure about the attachments of your balance matching up to the attachments of the S350 replacement channel balance purchase S350-20 with the option of 1950. If you are unsure that you need the S350, please submit a few pictures of both the top and bottom of your channel balance. |
