hand crank for crestline casement window

A quick learner from Modena, NY says:
Someone used too much force on the crank, with the latches engaged. I can screw the crank into the mechanism and open the window fine, but trying to close the window the crank unscrews itself. Whatever was holding the crank to the bracket is no longer effective.

Hi there!

It looks like the worm gear came out with your handle. Unfortunately, when this happens, it means the entire operator has broken down and needs to be replaced. Start by taking a look at our 39-031 & 39-032 or the 39-155 & 39-156 operators. Carefully look over the dimensions for each and see if any match your original assembly.
