Hello, thank you for posting,

Your pivot shoe resembles the 15-177 that is compatible with the Series 152 coil springs. Please review the dimensions below to confirm a good fit!

If you need assistance with choosing the correct weighted springs, please provide the weight of the window sash to move forward. The sash will need to be removed and placed on a scale. Thank you!
