Thanks for posting. Our Series 351 channel balance will not replace this. You have a special kind of balance that will have to be a custom order. We're close to knowing exactly what you have, I just have a couple details I need you to confirm.

Would you be able to show me a clearer picture of the metal hook at the end of the cord? I can't quite make it out from these photos, and seeing it will allow us to confirm what you have. I'd also like to see a photo of the top nylon attachment and of the stamp printed on the metal channel. Finally, can you also tell me how many you need?

Once I have this information, I'll email you an order link and price quote for the requested quantity.
