Top window hinges so window doesn't fall out

Hello there. This looks like the slide piece on a casement window hinge. I am afraid this component is not meant to be replaced on its own. When it breaks, it's a sign that the entire hinge set in the window should be replaced. See if our 36-048 10" Hinge Set matches what you have. See the dimensions below and let us know if anything differs.
