Hello, thank you for posting,
Please review the 15-087 coil pivot along with the 15-086 tandem housing. Compare the dimensions to confirm a good fit! These parts are compatible with the Series 180 coils springs. To determine the correct weighted options needed for your window, please provide the weight of the window sash to move forward. The sash will need to be removed and placed on a bathroom scale. Thank you!
