1840 B.S.I. Window Channel Balance

Question

I need to replace the channel balances of several (not sure exactly how many at the moment) windows. The only inscription on the part is 1840. They are 19" long. I see you have several that look appropriate. What is the difference between the "series" numbers?

Thanks for your help.

Hello Mary. Our S390-19 channel balance with a 1840 option should be able to be used as a replacement. Take a look and let us know if you agree.
