Channel Balance Replacement

Thanks for posting. This looks like an S795-30 Channel Balance, stamped 30B. The only outstanding issue is the T-Lock Shoe at the bottom. The Series 795 comes by default with the 15-195 1-1/4" wide shoe attached. There are a number of other T-Lock Shoes that this balance Series uses, however, including the 15-194 1" wide shoe and 15-195B 1-1/4" shoe that has an open cam (this simply means you can see 'through' the back wall of it; this affects compatibility with different pivot bars). These other shoes are sold separately. Without seeing your balance and shoe removed from the window I can't confirm which of these you need. Please check. If it turns out you need a shoe other than the 15-195, the process of swapping out shoes is pretty simple. See the video below. Let me know if you have any questions.

Our 15-195 is the closed cam version. Yours looks more like our 15-195B, which is also 1-1/4" but is open, meaning it has that rectangular hole in the back. I think this may be a better option for you.
