S390-28 28" Series 390 Channel Balance

Trying to find the right replacement. The channel is 5/8 but I assume 9/16 is what I need. It is 28" long. You will see stamp on photo is 2790__30 with B.S.I. and OJ on it.

I need 16 balances but I'm getting any where with the number that was given to me from a email I sent with pictures. I think I need the 2750 ones but not sure one person at your company says I need the the 850 series so I do not know what is what here.

Can I order these on line if so email me the number so I can go and process the order now thanks. I need the number that you use to match mine thanks

A customer has a window with the balances out. The top attachment on one is broken. The bottom of the other is broken. Your video explains install, but I need parts. Can you identify this model from pics?

On one small window Balance its printed 2740F and on another high windows its printed 3420. Both balances are 28" long, the metal part.

It appears that the balance on many of my windows is not working properly. My hopes is that by replacing the balances on many of these windows, that it'll save me having to buy new windows. Can you confirm the part that I need for this model? See images. THANK YOU!!!

Not sure which one to choose. My sash says 27 3 Caldwell IM.
