The Gateway series uses the pressure mount system rated #1 by a leading independent consumer organization. This premier gate installs quickly without tools or hardware, leaving no holes to damage walls or woodwork. Constructed of strong tubular steel, the U-shaped frame remains firmly installed while the center walk-through door opens in either direction. At 42" tall it's great for the safety of children and confinement of large dogs while also helping owners prevent bad habits like jumping and climbing.
