Replacement Window Coil Balance

Hi Chad, thank you for posting,

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

We do not carry a 10 pound weighted spring. To move forward, are you able to provide the weight of the window sash? Thank you! 

Hello, 

Yes, the sash is the moveable part of the window that is lifted and closed to open the window. This part will need to be removed and placed on a bathroom scale to get the weight to confirm the correct strength of the coil springs needed to keep the sash open when lifted. Thank you! 

Hello,

As long as the original was removed and measured to match the dimensions above, these parts should work well for your window. 

Once we have the window sash weight, we can determine the correct weighted springs to support the sash. 

Thank you,

For a 14 pound window, you can use (1) S152-7 coil spring on each side of the window. If you need a new coil support, please see the 15-143 bushing, 15-144 bushing cap and 15-145 support barrel. 

Please review and let me know if you have any additional questions!
