Cranks for opening and closing Casement windows

Hello! I will do my best to help. Before we can make a recommendation, I'll need you to remove the original from the window and show me a clear picture of it without obstruction. Please make sure the version you show us is as undamaged as possible, too. Thank you!

That looks like the same kind of handle used in operators like our 39-268. Unfortunately, we don't sell this by itself anymore. We can only offer the complete kit. I apologize for the inconvenience.
