The Kidco G15 Center Gateway White now extends to 6' with optional G15 extension pieces. The G15 Center Gateway by Kidco is a TOP RATED pressure mounted gate that installs quickly without tools or hardware, leaving no holes to damage walls or woodwork. The U-shaped frame remains firmly installed while the center walk-through door opens in either direction. The basic Kidco G15 Center Gateway® fits openings 29" to 37" wide. Constructed of tubular steel and 29½" tall, it's great for kids and pets, too.
