Hey Mark. The Dometic FanTastic Ultra Breeze Trailer Roof Vent Cover item # DMC38FR does limit the cover on your Fantastic Fan model 3350 from fully opening. The lift motor will stop once it feels resistance and will hold that position without any problems. It does not affect the motor or wear it down.
What kind of trailer or motorhome do you have?

Units were easy to install profile fits the exhaust fan perfectly. Keep the rain out and lets you have the vent open. I also installed the screens on the inside of the exhaust opening to help keep the instects out.
