Replacement channel balance

A home owner from Hawaii says:
My windows are stamped Empire Pacific 1985 and original since home built in 1988. Some balances are stamped 1830 and others are stamped 1940. Can you assist with purchase of 4 each replacements for the 1830 and 12 each of the 1940 channel balances?

Thank you

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.
