I need constant force springs

Question

My window weighs 15 lbs and there is one spring on each side. The springs are 1/2' wide and have 932 stamped on them.

Two windows are totally broken so I need four springs. Please see attached pics for reference.

Thanks,
John

Hello,

Your pivot shoe looks like an older version of the 15-180, which uses the S190 coil springs. Your original 932 coil stamp would generally correlate to the S190-940 but that would support an 18-pound window. If yours only weighs 15-pounds, I would recommend using the 190-840 on each side instead. Take a look and thanks for posting!
