Acvuweld casement window crank . Windows installed around 2001

Thanks for posting. I really can't say for sure what you need without seeing pictures of the old hardware, or knowing the size of the spline that your old crank handle attached to. If you just need the crank handle, confirm that the diameter of the spline is 11/32". If so, see our 39-205 Folding Crank Handle. Keep in mind that if the worm gear has come out of the operator along with the crank handle, then your operator is worn down and needs to be replaced as well.
