Meaning of "28 C" on a window channel balance?
On a single hung window's channel balance is stamped 28 C. 28 is the length (actual length of the metalic portion is 29 inch), what does "C" mean?
Where is the best place to buy replacement, big box hardware store, amazon, or ?? The replacements I see at those stores look slightly different than what I have which may require slight modifications.

It's a weight rating commonly associated with the numbered "30" balances.
Stamp Option (Sash Weight Range)
B 16 to 22 lbs
C 22 to 27 lbs
D 27 to 32 lbs
I use swisco a lot but you can find channel balances multiple places online. Primarily I'd be concerned with looking for the style that you have... if it even exists. Since yours are quite unusual I would probably look at the strybuc catalog first. The nylon bottom bracket looks like their Weathervane 900-15344 on page 22, with their 60 series balance. But you would need to measure everything to be sure it matches.
If it is weathervane, you can narrow your google search by including that in your searches.

Thanks.
The shoe does look like weathervane 15-193, but I can't figure how to buy the balances themselves.
On this page

It seems all the balances already come with shoes installed, but not the shoe I need. There is one without shoes S745 but it doesn't come in the size I need.
Should I be ordering bare balances (no shoes) elsewhere like homedepot or amazon, and order the shoes, rivets, rivet tool from swisco? Or should I also order the balances with the wrong shoes from swisco, remove the shoes and install the right ones?

If you read their customer questions and answers you would find that they can assemble them for you. Just make your request and they will prepare you a quote.

Or you can order the individual parts with rivets and do it yourself. I'd probably have them do it.

Do you feel that that they need some work? or is this a superficial issue?
Should I trust these windows to hold a 70lb AC?
Thank you :)
