Window casement arm. A63R. A63L

Thanks for reaching out! I suggest starting with our 36-048. Compare the dimensions to your existing hardware to confirm that this is the correct replacement for you.

You will need to replace both the top and bottom hinge to make sure the hinges match and to maintain the integrity of the function of your window. These can be used for both the left and right side of the window. Also, keep in mind, you will likely need to drill new holes to install these.
