Hi.
I need to replace the entire spring/coil system on one window (case and foot as well) for both sides of the window. The weight of the sash is 16lbs.
Can you please let me know what parts I need to order.
Thank you,
Melissa

Hello,

Take a look at our 15-180 balance shoe, which is used with the Series 190 coil springs, and see how the dimensions compare to your existing hardware. 

For a 16-pound sash, you would use one of the S190-840 springs on each side. Thanks for posting!
