I watched your video on how to replace a broken handle operator replacement. You showed in the video that there's a cut-out that allows the arm to detach from the slot bracket. My problem is the arm falls out of the cut-out when you're opening and closing the window. My slot bracket is 11 1/2". How best can I deal with the above issue so the operator handle doesn't fall out of the slot bracket when opening and closing the casement window?
Thank you, Don S
