Casement window crank handles

A home owner from Oak Grove, Missouri says:

I am looking for some replacement cranks/handles for casement windows. I believe they are Atrium windows, but not sure. These windows would be about 13 to 15 years old. The angular part of the stem of the crank is about 2 1/2 " long. the size/shape does not have to be exact however. The crank locks to the shaft of the window mechanism with a set screw. I would like to get 3 if I could please. I will attach a couple of photos. Any help you could give me would be appreciated. Thank you.

Thanks for posting. We will definitely try our best to help. Can you confirm the diameter of the hole that installs over the operator?

The post on the operator is 1/4" diameter.

I'm afraid I haven't been able to find anything in that size. Can you confirm? That measurement can get pretty specific, even going into the X/32" range.

The diameter of the opening on the crank handle is 11/32". The post on the operator does appear to be 1/4" diam plus the 'fins'. Thanks again for your help. Sorry for the delay in the response.

Ah, I see. If it's 11/32", then see our 39-114, I think you'll find this is a good match.
