Jealousies crank

Hey there! This is an old operator that was made by Stanley, and unfortunately it is no longer available. Years ago on a job I had to replace an operator just like this, and I was able to use a jalousie operator like the 39-165K or 39-346 to get the job done. Take a look at both of these items and see if you think either could work for you. As for the arc on the operator, as long as the link arm of the operator is the correct length to open and close the window you should be fine. Let us know if you have questions.
