Broken part for Guardian storm window
This is an image of the unbroken one
I have a broken storm window on a guardian screen door. The piece that is broken is the 'hanger' that keeps the storm window in the track (note--not the retractable ones on a spring, but the actual fixed-in-place hangers not sure what to call them that the window rides on). The whole piece is about 1.5-in. long and sticks into the track maybe 1/4-1/3 of an inch. Any idea where I can get this part, or does the entire window need to be replaced?
