Crank Handle

Thanks for posting. I am confident we can help replace this awning operator, but this looks like many different possible choices. The only way to know for sure what you need is to remove the old one and show us a rear view, so we can see clearly the top and bottom tabs with the mounting holes. We also need a side view of the link arm that comes out the back of the operator, fully removed from the window so we can see the hole at its end. We should be able to narrow this down from there.

Start by looking at the 39-012 or 39-278 Awning Operators. They seem to have similar hole pattern and link arm designs. See if you think one of these is a good match.
