Need 2 different window CHANNEL BALANCES,

A quick learner from San Francisco, CA 94118 says:
I need two different window channel balances:

2040-K B.S.I. 21 inch long bar, 0.5 inch wide
Quantity needed: 7

2090-I B.S.I. 21 inch long bar, 0.5 inch wide
Quantity needed: 3

I have uploaded a PDF with pictures of the markings and end caps

Can I order them from you?

Yours, Roger

Thanks for posting, Roger. Check out our Series 385 channel balance and Series 390 channel balance. These appear to match what you have. Specifically, I'd recommend our S385-21 and S390-21. I think you have the 2040 option for one but for the 2090 stamp, you will need to weigh your sash to confirm which of ours will work.
