Looking for a window channel block and tackle balance

Hello, Dan. I'm pretty confident that I can help you get a replacement for this balance, but before I recommend anything I would like you to show me a photo of the pivot shoe at the bottom of the window. I think I might know what it is, but I don't want to make any assumptions at this stage.

Please let me know when you can get that for me. Thanks!

Perfect, thank you! I am very confident that our Series 795 is exactly what you were looking for. There's just one catch, which is that pivot shoe you just showed me: the Series 795 comes with a 1-1/4" wide 15-195 by default, which has a closed cam (meaning it's solid in the back). Yours, however, appears to have a hole in the back, meaning it's the open cam style. 

That means you will want to purchase our 15-195B separately. These just pop on and off the balance, so you can clip this in place once you receive them. The video below shows you how.
