Window Crank handle Replacements

I had installed many Atrium Windows back around 1992. Our windows that open have a gold tone crank handles on the window. Most of the cranks are now stripped. I am looking to purchase replacements. They connect to the window mechanism by a small screw used for a allen wrench on. The hole opening you can see that slips over the window mechanism is 5/16 in diameter. James

Thank you for your patience in this matter. Now, after extensive research, we haven't found an exact match, but check out our 39-274 and see if this could be a possible replacement.

Tom, what you suggested does not work, hole is to small and it does not have the design inside to grab on mechanism in my upper left photo.

I'm sorry to hear it didn't work out for you. Can you confirm that the hole opening is 5/16"? It sounds like it's a little bigger. Would our 39-104 work? You should triple check your measurements just to be sure.
