Andersen Casement Window Crank Handles and Latch
Hi there!
Thank you for your patience during our busy season. We'd be happy to help but we'd like to see a photo of your operator with the window open so that the arms that move the sash are fully visible. Once we can identify the operator, we can determine which handles are compatible with your assembly.
As for the lock, look over the dimensions for our 38-056 and 38-057 Andersen casement locks and see if these match your original hardware.
It's hard to make out the operator's entire arm(s) from these pictures, but start by taking a look at our 39-146 and 39-147 Andersen window operators. These are also compatible with the 39-286 window handle. I can't guarantee this is what you have but carefully look over our dimensions and compare them to your original assembly to see if this matches up for what you need.
