Hello! Thanks for reaching out to us. I'm sorry to say that I don't recognize the piece in your window and don't really have any idea what it might be. It looks too thick to be a spring, while at the same time too thin to be anything else. Odds are its an internal mechanism of some kind, fallen out of a larger assembly. Your best bet is to probably check another, identical window in the house to see what kind of hardware it uses and to see if you can spy this component amongst the other pieces installed on that window. |
