Window crank handle Replacements.

Your picture is a little blurry so I'm not sure exactly what this is. Is that stem a 5/16" hex? If so, you could possibly use our 39-226 as a replacement. Look it over and see what you think.

Hey, Bob. These old hex handles were held in with little metal collars in the operator. These had a habit of breaking so that's probably what happened to yours, too. Unfortunately, they can't be replaced or repaired. Odds are the operator isn't made anymore, either, since "female" operators fell out of style years ago. The reason they did that was probably because the old ones broke so often, though I'm just guessing.

You don't have many options if you want to keep using the operators. You could try padding the hex out with scotch tape or even just glue it in. I've done both with satisfactory results, though neither is ideal and I personally don't like using glue that much. 

I'm sorry that we couldn't offer you an easier solution.
