The crank for the window is broken, I need to replace a couple- not sure brand? It is metal not plastic about 10 years old

A handy person from Chicago says:
I have 10 year old windows and a couple have broken cranks. I am looking to replace just the handles as the actual window
Crank still works fine. They are metal but the base is a hard plastic? No name on the windows it was a spec home if that helps.

No need to supply a brand, I think I know something that could work. Take a look at our 39-376 and 39-375 folding handles. Check the dimensions against your old handle to see if it is a match.
