Need 2 sets of all of the parts shown for Champion vinyl double hung. The sash is 18 inches high by 32 inches wide with insulated glass. Not sure how that equates to the coil pounds. Thank you.

Thanks for posting. The pivot shoe looks like the 15-177, which uses Series 152 Coil Balance springs. These replacement springs are screwed to the new shoe with a fastener like the 33-072. The pivot bar might be the 26-226, but review to confirm.

To determine the coil spring weights, look for stamps on the old coil springs. If there are none you'll need to weigh the window sash. The video below explains.

Hi Bob,
Thank you for the reply. Upon another look, I do see an E7 on the broken coil spring. So does that indicate 7 lbs?
The other parts you show seem to be correct.
Thank you.

Yep! That would indicate you'd need the S152-7 7 pound spring. Let us know if you have further questions.
