Looking to replace the crank

Thanks for posting! Your casement operator looks like it could be our 39-140 or perhaps one similar to it. Look over the dimensions and compare them to your existing operator to determine if this is the right fit. The compatible crank handle is part 39-114L.

If it is not a match, please send a photo of the entire operator and I'd be happy to search for a better solution.
