Parts

Hello, thank you for posting,

Please start by reviewing the 15-192 pivot shoe that is compatible with the Series 170 coil springs. Compare all dimensions to confirm a good fit! For the #406 stamp, see the S170-406 coil that can support 6 pounds of weight. Together will the other side, the total sash weight should weigh 12 pounds.

Review all parts and let us know if you have any additional questions!
