Clothes Holder Hook This hook is designed specifically to hold up your clothes after they come out of the dryer or are taken off a hanger. It's perfect for people who have limited closet space and need a way to keep their clothes organized without having to hang them up. The hook can be mounted on a wall, placed in a corner, or even attached to the back of a door.
