This is for the left side of the window. The balance popped out and I guess the spring sprung up. Will you be able to help me match what I need? Thank you

Hello,

Your channel balances resembles the S770, which attaches to the top of the window with a screw and anchors to the pivot shoe with a terminal clip at the end of the pulley cord.

If the pivot shoe is the part that broke, I would recommend removing yours from the window to compare to the 15-129 shown below. Take a look and thanks for posting!

Hello
The length of my channel balance is 19" and the width is 1/2". The best I could read on the back looks like 19B BSI Does your S770 still resemble mine? And do you think the Pivot Shoe 15-129 would work? It looks a little bit too big. Thank you for helping me

Could it possibly be called a Block and Tackle Balance??

We do offer a 19B strength option for the S770-19 channel balance, which is also referred to as a block and tackle balance in the industry. The 15-129 is often used with the S770 but we would need to see your pivot shoe uninstalled, along with written-out dimensions, to confirm if a closer match is available.
