Thanks for posting. Before I can confirm what Series channel balance you have, I'll have to figure out what your bottom shoe is. Please look at the measurements for our 15-001 and 15-002 bottom shoes and note their depths. As you can see, they are 1-1/8" deep and 1" deep, respectively. Which measurement more closely resembles your own shoe?

Hi Tom,

Thank you very much for your quick response. My measurement is 1 1/8" which fits with your 15-001 bottom shoe then.

My next question, is of course, what is the correct part to replace my broken one?

Thanks sir!

In that case, how about our Series 390 channel balance? Does that look good to you?

Looks good for me. I will order with the 2730 option to be same with the original one. Once again, many thanks for your help!
