Window Balance Assembly Replacement

Home Owner from Lawrenceville GA
Hello, I am looking for a replacement window balance assembly in the photo. The only information about the windows I can find is that of the Quality Control & Testing AAMA Certification Program,

Series: 3500, AAMA/NWWDA 101/I.S. 2-97,
H-R20-48x78
H-R35*-36x66.


MI Windows & Doors 11153252.7
3500

Thanks much
Eric

Hi Eric, thank you for posting,

Your assembly resembles the 15-180 pivot shoe that is compatible with the Series 190 coil springs. Compare the dimensions below to confirm a good fit! Also see the 15-186 balance clip and 15-182 support barrel.

The original coil should have a number stamped into the metal that will indicate the weighted option needed. If there is no markings present, please provide the weight of the window sash to move forward. 

Let us know if you have any questions!
