Coil balance

A home owner from Youngstown OH says:
I have a 3inch double pane vinyl window. I need to replace the coil balance but I do not know exactly what I need. The manufacturer was Weather Tite Windows in Youngstown OH who is out of business. Would you be able to help with the parts? Please let me know if you need additional information

Hello,

Your photos resemble the 15-191 pivot shoe, which uses the Series 160 coil springs. Take a look and compare the specifications shown on our product pages to yours. 

As for the pivot bar, take a look at the 26-444. Thanks for posting!

I need the entire assembly with the coil. Can you suggest a part that would be compatible?

Sure. As we mentioned, your pivot shoe uses the S160 coil springs. You'll need to remove yours to confirm the stamp code printed on the coil base, which you'll use to choose the corresponding strength option. Also, see the 15-150S support.
