Vinyl window balance

A quick learner from Williamsport, MD says:
This is about 1 1/4" wide and 9/16" wide. There are no markings on the windows or this piece. As far as I can tell, the part that the window hooks in broke or disintegrated. Both the left and right sides need to be replaced.

Thanks for contacting us. Your pivot shoe is our 15-180. I posted some related parts on the right to further help you. For the Series 190 coil springs, you will need to match the numbers from the old springs. If nothing else is broken, the 15-180 may be all you need.
