Keeping your pets contained without sacrificing style and functionality has never been easier with the Walk-Through Pet Gate by Petmaker. This metal pet barrier features a swinging door that opens in both directions and a pressure mounting design that adjusts to the width of your doorway, hallway or threshold. Recommended for pet use only, this pet gate safely prevents pups from sneaking through the fence with narrow 2.25" openings between each pole. The pet gate also comes with a 4-inch expander kit for extra wide openings and requires no installation, drilling or hardware that could damage the wall of your home.
