I'm trying to order a replacement for a Wide Channel Balance. It is a non-tilt window that is 1/2 inch in width. I can not find a similar size, the serial number on the one I currently have is 212000H W.

It's hard to tell exactly what you have, but it looks like your nylon attachments once had wings that were broken off. Can you confirm? If so, I think you could have either our Series 380 or Series 385 channel balance, depending on the size of your shoe. That is the only difference between these two balances.
