Certainteed awning window roto operator




Thanks for posting! Your awning window operator appears to be similar to our 39-239C Encore Awning Operator. This operator is stainless steel so it may help with the corrosion you are experiencing with your current awning operator. This operator is compatible with either the 39-375 folding or 39-451 non-folding handle and cover kits.
You may also need the 39-558 Detach Clip.
Look over the dimension and design of this operator and carefully compare them to your existing hardware to confirm that this is the operator needed for your window.







I'm glad to hear that the operator was a fit and that I could be of help to you.
Please feel free to reach out with any other hardware repair questions!
Have a great day!
