window crank

Hey Natalia. I am confident we can help, but we'll need a better view of this awning operator's link arm, fully removed from the window. The configuration of the link as well as the hole at its end is critical to see. Also, judging from your sketch it looks like the top tab has one screw hole, and the bottom tab has two. If that is incorrect, please send us a picture of the operator from the rear so we can confirm. From there we should be able to narrow down possible replacements. 

Hey Natalia, thanks for getting back to me. This operator might be our 39-194, which has a similar hole spread and also has that bend in the link arm seen in your old assembly. But I still advise you remove the old mechanism fully and compare to the diagram below to confirm it matches up. You need to make sure that hole at the end of the link arm is 3/8". Let me know if anything differs, or if you have any other questions.
