Series 850 Block and Tackle Rod Balance
I did see you have another item that can replace it, and I think the previous owner of my house has installed them already too. As I was doing some research, trying to find a good one in my house, I found that some of the windows have a 33c channel balance. I think it's the Series 795 Channel Balances 33c. I removed one of those to see if it had a manufacturer name on them but they didn't fit perfectly so getting them back in was tricky. no brand name.
I need 4 of these.. best advice on which ones to get would be great.
We appreciate your patience. I am afraid the cross bow balance you are looking is no longer offered. We now offer another alternative replacement that should work just as well. Please take a look at our S795-34 balance. This comes assembled with the 1" T-lock balance shoe that accommodates your 15/16" pivot shoe. In order to determine the option on the new balance, weigh your sash on a scale and correspond that to the sash weight chart on the product page.
You will also need to change the pivot bar. Send us a photo of your current part and we will see what replacement options there are for you.
Thank you for getting back to us! Like Paul said, it sounds like our S795-34 with a 34B option will work well for you. I'm afraid he misspoke in his original post, though: the S795-34 comes with a 1-1/4" wide shoe, not 1". The 1" wide shoe is our 15-194 and is sold separately, however they just pop on and off easily enough. See the video related to this thread.
I would also recommend the 26-021 pivot bar.
Great! Let us know if you ever need anything else.
