Jalousie Operator Handle

Hello! We sell replacement crank handles of a variety of sizes, but I'm not sure what size would work best for this application. Before we go any further, can you please tell me the exact diameter of the hole? I can then check our inventory for a match.

Thank you! The only handle we sell that has a 5/16" spline like this is our 39-274. As it turns out, this is commonly used on older casement, jalousie, and awning windows, but not necessarily as old as yours. Therefore I cannot say for sure that it will work for you, only that it is the best possible match we can offer. Look it over and let me know if you had any questions.

The 39-274 doesn't have any grooves or ribs on the inside of the hole. As I mentioned before, I can't guarantee that this is going to work for you, but it's the only size we carry that might.

I'm very sorry to hear that, but I understand. Please feel free to reach out if you had any follow up questions. Otherwise, best of luck with this project!
