Hello, thank you for posting,

Please start by reviewing the style and dimensions of the 15-192 pivot shoe to see how it compares to your original. This pivot shoe is compatible with the Series 170 and Series 171 coil springs. The original coil should have a number stamped that indicates the weighted option needed to support the window sash.

 Please review and let us know if you have any additional questions!
