Wood Casement Crank Handle Replacement Needed

A quick learner says:
The current handle I have is your part 39-347 which is too small for my window. Looks like it needs to be about 3/8" to work for mine. I can't find anything bigger than 1/4" anywhere. Anyone know where to find one?

I haven't been able to find a crank handle in that size, either, I'm afraid. You may want to consider replacing the whole operator with something like our 39-268. This looks similar to what you have, though I'm not sure if the arm is the same. Sorry we couldn't offer a better solution!
