Crank on a jal-o-vent window

A home owner from Oak lawn, IL says:
I have a jal-o-vent window in which the crank to open up the vents has stopped working (in fact I have 2, upstairs and downstairs bathrooms). The opening of the window is 15x15. Can use suggest a hardware that might work?

Thanks for posting. Could you remove your operator from the window and provide pictures of it, including any link arm(s)? This will be useful in finding a replacement. Thanks!

Take a look at the 39-005 standard jalousie operator, along with our 39-346 jalousie kit. See which one would work best for your window.
