I have been trying to find replacement parts for a cranking window at my house. There is only one marking on them and it says interlock. Our house is on the ocean so metal rust fast and I need to replace about six of theses. Thanks for the help.

I think you might have our 39-239 operator. Carefully look it over and let me know what you think.
