A handy person from Minnesota says:

channel balance approx 24" see photo 2: "23-5 AT5 CMC 34" (but is rusted to left)

What series do I need?

I believe these are balances that use the 19-041 Top Fitting as well as the 15-004 1-3/32" deep Bottom Shoe. Please compare to confirm. If so, none of our standard balances have this attachment combo but we can provide them to you via custom order. I just shot you an email with a purchase link enclosed to order six(6) as requested. Let me know if you have any other questions, or if the fittings don't match, prior to placing your order.

A handy person from Minnesota says:
I don't have one physically with me here, but I will be in Florida next week to look, and place an order then.
If you can give me any more details to identify which fittings I have, please do. Just what is 1-3/32" ?

The 1-3/32" measurement is the depth. You can see what I mean in the diagram below. If this depth measurement is at all different on yours, please let us know and we can find something closer.

Once I can pull one out af a window, I can send closeup pics of the caps if it's unclear.
