looking for replacement Truth casement operator - installed on Marvin Integrity windows Original model #45251. Purchased new 39-318 and 39-317 as replacements and they were too short and didn't close the window. Is there another model that we could use.

Hi there!

We've seen this operator a few times in the past but I'm afraid we don't have an exact match. I'd say a better option would be our 39-171 and 39-172. The offset is a bit more dramatic but it may not be a big deal. It is our best option, however. Look these two parts over and see what you think.
