Hello, I'm looking for double/dual-type coil springs for 20 year old certainteed windows. The sash weighs approximately 9 lbs (used bathroom-type scale). Please see the part numbers in the photo. Thank you!

Hi there!

Thank you for reaching out to us. I recommend our 15-192 pivot shoe which uses the S170 and S171 coil springs. For new coil covers, see the 15-156 or 15-185 depending on the dimensions. 

To determine the proper spring weights, you will need to divide the sash weight by the total number of springs in the window.
