Option to use between 2110, 2120, 2130, 2140, and 2150

A quick learner from Roseburg, Oregon says:
After looking at your web site, I'm pretty sure the channel balance I need is a S385-22. I'm not sure of the option I need. The metal part of the balance is 22 inches long and the channel is half an inch wide. Your help would be greatly appreciated.

Does the top nylon fitting have wings, or tabs on each side, like our 19-005? If so, you actually need our S395-22 Channel Balance. Your old balance's stamp code of 21-4 conforms to our stamp option of 2140, so that's the one you should pick. Let me know if you have further questions.

Thanks Bob for your wise wisdom. I ordered your S395-22 Channel Balances and they worked like a gem. I also appreciate that it only took two days to ship them out to Oregon. Thanks again.
