Milgard awning windows
Hello, thank you for posting,
Your awning operator resembles the 39-239B that is also available in the 39-239C stainless steel version. Please review the overall style and dimensions to confirm a good fit. For a new cover, review the 39-375.
Unfortunately we do not carry this exact sized hinge assembly. The best we are able to provide is the 36-004-14 29- bar hinge hinge. We believe these hinges have a chance of working for your window even though they are not as long as your originals. Take a look at the overall style and dimensions to see what you think! Both sides of the hinge will need to be replaced at the same time.
Let us know if you have any additional questions!
