Regalo Easy Step Extra Tall Walk Thru Baby Safety Gate, Fits Openings 29-36.5 Inches, Black

It does take 2 hands to open but can be closed with 1 hand. I used the pressure mount method versus screwing it into the door frame and my grown son was able to accidentally knock it down. But it was very easy to install and reinstall after being knocked down. When measuring the height, measure to the bottom of the doorknob if you intend to close the door behind it.

We think this will keep a four-year-old autistic boy out of the small kitchen where he climbed cabinets and the refrigerator. He quickly learned to undo the refrigerator locks so this is our main hope for keeping him safely out. I used the option of blocking the rubber "feet" from slipping along the slick painted sheetrock wall. The boy is very strong, but seems to have given up on attempts to get through the gate.
