Window crank

Thanks for writing in. For a new crank handle, see our 39-114L. Just make sure the diameter of the spline that accepts the handle is 11/32". You may want to make sure the splines themselves aren't stripped; if you have a handle that's still undamaged, try testing it on the other operators to see if they work. If it doesn't, then you may need to replace the entire casement operator. We can help you with this but we'd need to see it out of the window, with the link arm(s) in full view. Many thanks.
