Looking fore replacement Marvin crank

A handy person from Durango, Co says:
While the crank itself has no markings on it, the cover has the Marvin name on the inside of it. We're simply looking for the crank, or a replacement for it

Thanks for posting. Take a look at our 39-107FK folding handle and cover, which appears to be our closest match. This is used on Truth casement operators with a 11/32" size spline. Is that the same size as your own spline? This is probably the most important detail when it comes to replacing crank handles, so it's a good idea to double check.

If you are not sure, send us some photos of your handle removed from the operator. Also include the size of the spline on which the handle goes.

Thanks Dave! Does this mean I am just purchasing the item above for both the crank and the cover? The cover will replace my old cover?

Thanks,
Drew

Drew, the 39-107FK is a handle and cover in one.

However, like I stated above, the most important detail when replacing crank handles is the spline size. Please be sure to compare your spline to the 11/32" size spline on the 39-107FK.

And as always, you can upload some more pictures so we can take a look and try to help.
