Hello, Take a look at our 15-180 pivot shoe that uses the Series 190 coil springs. Look over these parts and the related items to replace any damaged parts of your coil balance assembly. If none of your coils have a stamp, you'll need to weigh the window sash and divide the weight by the number of coils in the window to choose the correct strength option. Thanks for posting! |
