My Superior Window need to replace 2 balancers and I couldn't locate the correct parts. I took the balancer out to measure the Top is
19-002, the
shoes I'm not sure it is
15-001 or
15-002 because it measures 1 1/16" width,
the length is 24" metal only, the sash weighs 20 lbs. Please help is it S351
or S390
Thank you.
Edward
