The only thing I found on the channel balance is 281/4 3 picture is attached

We may be able to replace this balance, but due to its special length it will have to be a custom order. Before we begin, can you confirm what style the bottom nylon fitting is? It will be either our 15-001 (1-1/8" deep) or 15-002 (1" deep). Carefully look over our photos and dimensions to confirm.

Can you also tell me how many you need? 

In the meantime, we'll keep researching to see if this is something that we can provide.
