I forgot to mention that these are single hung, non-tilt windows.

Thanks

Without referencing the original balances, there is no way we can guarantee what it is you have. That said, many Viking windows have used our Series 395 channel balance. Could this be what you have? As for the size, can you tell me the height of the visible glass of the sash these balances support? That will tell us what length you need. Thanks!
