Baby Safety Gate for Stairs, 29.5-51.6" Extra Wide with Extensions, Auto-Close Metal Walk Through Dog Gate for Doorways and Narrow, Pressure Mounted No Drilling. [29.5 - 51.6 Inches]- Wide baby gate can be installed in any opening width within 29.5-51.6 inches. The 30-inch height is in line with the design that most people can open with one hand without bending over. The man-passable width is 23.7 inches. (Please measure your opening distance before purchasing.) [Double Security Lock] - Walk-thru baby gate needs three steps to open the door lock, and the special structure of the double lock can be opened by one hand for adults, but it’s complicated and difficult to open for babies and pets. [Easy to Install] - Baby gate with door installation can be done quickly without drilling or other tools. The fixing principle is pressure installation. So when there is a gap between the door locks or the wall is uneven (with skirting lines), the tension bolts on both sides can be adjusted. Suitable for installation on stairs, hallways or doorways. [Durable] - The all-steel manufacturing metal baby gate with door can resist 150 pounds of impact, without worrying about the energy of your children and the destructive power of pets. [Auto-Close] - The gate door can be opened in both directions, when the door is opened to 90°, it can remain open; when it is less than 90°, the door will automatically close. See less
