Four fir wood panels linked by metal hinges rotate a full 180 degrees, so this gray dog gate folds around a stair landing, a hallway turn or a straight doorway. Fully expanded it spans 83-in and stands 30-in tall, and it holds position without screws, brackets or pressure mounts against the wall. Natural fir keeps the frame stiff without adding bulk, and the whole gate weighs just 5.5 lbs in total. When the room needs to open up, the panels collapse to 21-in by 2.2-in and slide behind a door or into a closet. Small dogs, medium dogs, puppies and cats all read it as a wall.
