Simonton window

Hello, thank you for posting,

Your window uses an older Simonton coil balance that is no longer made. We recommend converting the 15-259 pivot shoe and Series 159 coil springs along with the 26-083 pivot bar. 

Please review the step by step video below that details the conversion and parts needed. If you need assistance with choosing the correct weighted coils, please provide the weight of the window sash to move forward.

Let me know if you have any additional questions!
