Double Hung Window Parts

Hello,

It's tough to tell with the pivot shoe still installed but start by comparing the width and thickness of our 15-046 to yours once it's removed from the window. The pivot bar in your photo looks similar to our 26-400. Carefully compare the dimensions to your parts and let us know what you come up with. We have other possible replacements if one of these doesn't match up. Thank you!

It's always best to see a channel balance removed from the window to confirm the series but I agree that your balance looks like the S765-16 with a spring strength option of 15-3.

To remove an S765 balance, you'll need to stick a flat-head screwdriver in the pivot shoe's cam and turn it, which will unlock it. Gently slide it up to the balance, careful not to let it shoot up, and disconnect the hook from the shoe. Finally, simply unscrew the top of the balance and take it out. You may want to use needlenose pliers when installing the new balance since, as you mentioned, there is no way to secure a charging tool to the terminal clip as we demonstrate in our video, The rest of the process is explained in our tilt window balance removal video below. Thank you!
