Wind caught the door and pushed it open, hard. Now the door seems to be sagging a little. It closes hard and there are signs of wear on the striker. Anyone know how to adjust the door?

I believe its a 10mm triple square socket that you use to loosen up the striker a little then tap it with a small hammer to move it arround ( move it in to make the door go in, move it out to make the door go out, when its closed that is).

Thanks! The problem seems to be with the hinges since the door does not fit into the opening properly. I can lower the striker plate but the door will still sag in the opening. Do these hinges wear out or break? Can they be ordered and replaced?
