Thanks for posting. While the stamped numbers are important, they only tell us the strength of the spring inside each particular channel balance. The size and style of the channel balance and its end attachments are what matters most in identifying a replacement. If you could provide pictures of the end attachments, as well as measure the length of each metal channel (not including the end attachments), then we can help you find your new balances. See the video below for details. |
