Two different windows

Question

Hi
For the single coil I believe the plastic piece holding the coil has a "F" or "L" on it and the coil itself has a "F" or "P" on it. I'm looking to replace both assemblies for the window. For the double coil the coil has a "CL" on it then the bottom plastic piece reads "D" and the top plastic "L" I need both assemblies for the window.

Thank you

Hello, thank you for posting,

Even though the pivot shoes look slightly different, both windows should be able to be replaced with the 15-177 pivot shoe that is compatible with the Series 152 coil springs. Please review the dimensions below to confirm a good fit!

Since there are no number markings on the springs, we will need to know the weight of each window sash. The sashes will need to be removed and placed on a bathroom scale. From there we can move forward with the correct weighted coils.

Also see the 15-143 bushing, 15-144 bushing cap and 15-145 support barrel for each coil spring. Let me know if you have any questions!
