Window cranks

Thanks for posting, Lenora. We should be able to supply a match for these operators, but your photos only show the base. We will also need to see the arms that physically open and close the windows. That will tell the other half of the story. Let me know whenever you can get those photos to me.

Thank you! This operator looks very similar in design to our 39-188, and I do think this product is our best match, but there's one major and obvious difference: your link arm is much longer than ours.

That may be a problem. I just couldn't find anything with a link arm in that same size. You could try the 39-188 and see if it works as-is, but if not then the only solution we can recommend would be to swap the link arms between the old and new operator. You'd have to drill them out, then install your old link arm on the 39-188 operator using a 39-188 rivet, which must be hammered into shape. Would that work for you?
