Please help to select a channel balance

Question

Hi,
The top attached of the channel balance was broken on both side and the string was broken on one side. Here is the measurement of the channel balance: non-tilted window 1/2 wide X 28 inch long. The number on the channel is 2730 BSI. The top attached looks like 19-005. I want to replace both channel balance. However, series 350, 351, 385 and 390 are looked the same to me.
- Which channel balance I should choose?
- What type of top attached, rivet I should choose if I want to replace the top attached only?

Thanks.
Maynard

Thanks for posting. Before I can offer the appropriate Series channel balance for you, I just need to know a bit more info about the bottom attachment. Please review to the chart below to identify the shoe that most closely resembles your own. Keep in mind that while a fraction of an inch difference doesn't seem like much, it is in fact vital to the operation of your balance, and I highly encourage you to get as exact a measurement as you can.
