Hello, thank you for posting,

Your pivot shoe resembles the 15-180 that is compatible with the Series 190 coil springs. Please review the dimensions below to confirm a good fit!

Alternate image for 15-180

The original coil springs should have a number stamped on each coil that will determine the weighted option needed. If no markings are present, please provide the weight of the window sash to for further assistance.

Also see the 15-181 support clip and 15-182 balance bushing. Let us know if you have any questions!

Thank you. Lauren.

I checked but there is no markings.
The window's weight is around 24.5 LB.

Could you please let me know which parts should be ordered for the windows of mine ?
- 15-180/181/182 with coil balance, correct ?

Thank you.
Daniel.

Hi Daniel,

For a 24.5 pound window sash, you can use (2) S190-640 coil springs on each side of the window.

If replacing both sides, you would need.

(2) 15-180 pivot shoes

(4) S190-640 coils

(4) 15-182 balance bushings

(2) 15-181 support clips

Note if your original supports clips and bushings are in good shape, they can be reused.

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