I tried it on my 2014 WhiteHawk 30DSQB.....it is made to be placed in 3 different positions.....when positioned in front of the door the door cannot be opened......when we went thru our demo with our dealer, he said to always place it in front of the door when traveling as a safety measure to keep door from opening accidently while moving....one should be able, on our model, to open kitchen window next to door, remove screen, and reach outside and move the handle if someone were to lock you inside.....haven't tried that yet but I think I could reach it if necessary.
