Folding window crank for 3/8"? shaft

Hello,
I have casement windows with wooden shutters that no longer have handles. I tried using a universal fit handle but it performed poorly. I have also tried Ideal SK928 handles and Truth EP27034 handles but neither fit.

I have seen prior responses that Pella T handles for 3/8" spline may work but would prefer a folding handle.

Thanks,
Kevin C.

Hi Kevin. Can you show me the entire operator, including the link arm(s) that push and pull the window close? That would be the easiest way to identify the operator you have, and thus also the crank handles that can work for it. From there I'll do my best to ID what you need.

Picture of window partially open with lever and operator hub visible. I have tried several universal handles and they work fine one or two openings and then start to slip.

Thanks for posting. If the handle keeps slipping, I am afraid it's possible the gears in this operator are breaking down and should need to be replaced. This is an old operator that is no longer made, but you might be able to replace it with our 39-316 Operator, 39-105 Clip and 39-114L Handle. Look over the dimensions and see what you think.
