Also would like to know how to adjust window for it seems to come in closer on one side and not the other! I was trying to force the issue and the operator came apart At the handle. I can still pull the window closed with my hands, but not all the way!

Hello there. I believe this operator might be our 39-348. Take a look and see if you agree. For a crank handle that works with this operator, see our 39-114L.
