when the closet doors slam with the seas, you should...
1) check to make sure that they are not reversed, the latching stuff is only on one side and if the doors are reversed then there is nothing for them to latch to.
2) for really heavy motion, close the doors and in the middle junction stuff a folded washcloth.
this takes care of the doors, but you still get that annoying hanger noise on the last night, since the closet is mostly empty.
