The KidCo Auto-Close Gateway is a pressure mounted gate that utilizes our Magnet-Lock Technology to automatically draw the door closed and guarantee it locks each and every time. It also has a hold open feature for those times where the door needs to stay open until it is pushed closed. Perfect for heavily traveled doorways and/or room openings. No tools needed for installation. Optional extensions are available for wider openings to 47 ½”. Note: KidCo does not recommend pressure mount gates for top of stairs use, even with hardware mounted wall cups. There is a bar at the bottom of all pressure mount gates that helps keep the gate in place and this bar can be a tripping hazard when placed at the top of stairs.
