I believe I have either the Series 351 or the 390 channel balance. Please help to identify. Stamp on the channel reads "28 3 HL CALDWELL."

Thanks!

Hey, thanks for posting. I've narrowed this down to two possible channel balance Series: either our Series 351 or our Series 390 balances.

Now, as you can see, there is only one difference between these two Series, and that is their bottom shoe. The Series 351 uses the 15-002 while the Series 390 uses the 15-001. I can't quite tell what you have based on your pictures, though. Please carefully compare their dimensions to your own hardware and see which is a better match.

I'm sorry, I'm not sure if you understood my response. I already know the length of the metal channel. Please read the reply I posted above to determine what balance you need.
