Casement hinges and cranks
Thanks for posting! Your awning window crank reminds me of the 39-239B Encore Awning Operator (also available in stainless steel 39-239C). To confirm that this is the right replacement, you'll need to carefully look over the dimensions on the website and compare them.
The casement window operators can be replaced with either the 39-253LB or the 39-438B Encore Dual Arm Operators. To determine which of these is the correct replacement, you'll need to compare the differences as described in the video tutorial tagged below.
You'll find the compatible hardware and accessories for each of the recommended operators in their related products on the website.
Please feel free to reach out with any questions.
