Marvin window crank, sort of a low profile or "short throw" type

I believe our closest match to this nested handle and cover would be the 39-107FK. If the spline on your operator is centered and 11/32" in diameter, then I believe this would work as a replacement. Unfortunately we don't have anything with a shape quite like that. If you really want something that doesn't protrude, another possibility would be to use the 39-107 cover along with the 39-102 Tee Handle. Finally, you also could contact Marvin directly to see if they still make this particular style.
