BALANCE HELP

Thanks for posting. Take a look at our Series 390 Channel Balances. Could you confirm the length of the metal channel? Be sure not to include the end attachments in this measurement. I think this should actually be 17", but let us know if it isn't. Once you know what length to select, you will need to select a stamp option. 1620 conforms to a window sash weight range of 8 through 12 lbs. Let us know if you have any question.
