Bedroom door comes open during travel.

Regarding my pocket door...It does have a plastic strap with snap. Unfortunately the inner two screws fell out of the top track, so essentially the door is falling off the track, putting more pressure on the strap. I had someone install another strap near the bottom. He did such a crappy job, it may as well not be there.

The screw holes are impossible for me to access. I just wanted to see if anyone suggested a big thick door stop. Maybe I could glue two together, one on top of the other. I know I have to fix/tighten the door straps. But until I get to that.....
