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?

Great! In that case, take a look a tour Series 390 channel balance. I think you may need a 23" long channel and 17" long channel for your respective balances. For the options, I think the 22b stamp will correspond to our 2220 option, while the 16b stamp should correspond to our 1620 option, but I can't be certain. You will want to weigh your sash and compare it to the weight ranges shown for these options in order to know for sure. Let me know what you think!
