Parts for Vinyl Bathroom Window

A handy person from Croton-on-Hudson, NY says:

23 1/2 X 36 bathroom window. On both sides of window, the metal strap broke(coils?) Was told window was purchased from Jilco. Do not see any names/numbers on parts or window. Looks like coil snapped in middle. Seems to be attached to bottom piece. Top parts had rest of coil around bushing.

Thanks for your help

Thank you for posting. Before we can identify the coil spring, can you first confirm what shoe you have? I think it looks similar to our 15-180, but carefully compare them to make sure. If you agree, then I recommend our Series 190 coil spring. There should be a stamp on the spring itself to determine just what variety of Series 190 you need.
