Thanks for posting! That stamp tells us the strength of the channel balance, but not its identity, which is determined by the end attachments. It looks like the bottom fitting has wings, or those side tabs, while the top one does not. Is that accurate? If so, I believe this is an S350-28, with a stamp option of 2730. Let me know if you have further questions. |
