1960 Awning Window cranks

I am missing a few window cranks for my 1960 Awning windows. I tried your 5/16 crank. It was to small.

If you only need the handle, then we may be able to help. You mention that the 5/16" is too small, but not what size you actually need. Can you give me the exact size of the spline you need? Please be as precise as possible.

I tried a Marvin 7/16. It fits but the spline ridges do not line up. Looks like Marvin has 12 ridges but I need 16. I need a 7/16 with 16 spline ridges.

The only handle we have with a 7/16" hole diameter is our 39-195. This looks like it has fewer ridges than 16, but in my experience that doesn't always matter. The diameter of the hole is usually paramount.

7/16" is a very uncommon size. I would triple check that measurement to be sure.

I have tried a 3/8. It would not fit at all. The 7/16 Marvin replacement only slides on about 1/4 inch and will not go further because the ridges do not line up.
The handle I need should also have a 3/4 inch depth to the bore. I need it to slide on that far before I can engage the set screw.
These are 1960's windows in really very good shape. Mfg plate says Anderson, Bradenton FLA, Owensboro,KY, Rome, GA.

I believe we've tried to find your particular handle size in the past, but without any success. If none of the handle sizes we have work then you might need to replace the complete operator.

Take a look at the 39-054 to start out, but we also carry more on this page. See if any match up to the one you have.
