Champion window balance quick pivot

Hello!

Your pivot shoe is a match for the 15-177, which uses the Series 152 coil springs. They're designed to screw to the side of the pivot shoe with the 33-072. You'll have to check the band of the spring for a stamped weight code as well.

If you need new coil supports, see the 15-143, 15-144, and 15-145. 

Please let us know if you have any questions.
