How could I fix this door-stop?
After a meeting at church in one of the side-rooms, my attention was drawn to the pathetic nature of this door stop. People frequently come and go from the meeting (bathroom, etc.) and we want to keep the door cracked open a little, but the door stop is useless. it looks like somebody purposefully un-screwed the screw on the right to try to give the stop some more play, but it doesn't seemed to have helped at all. the big solid door just wants to swing shut all of the time (hence the addition of that second wedge-shaped door stop that only helps a little). Does anybody have any specific suggestions on how to fix this? Maybe scuff the bottom of the rubber pad to help it grip more? The floor looks like it's made of regularly waxed linoleum.
