Replace hinges on access door for easy removal

If you have a full length clearance on one side, that could work. My stairs and the bumper bracket flank this door. I had originally concidered that as an option but it would not work here. As installed, I can't remove the door when closed nor does it rattle. When open, it does not feel like it will fall off, but with a 2" push to the left it slides free and is released.
