The First Years Simple and Secure stair gate is designed to swing open easily - without pinching -- and close securely with a "click" sound to reassure it is locked. The push and turn lock is easy for an adult but too difficult for a child under two to open. The First Years Simple and Secure Stair Gate is hardware mounted to meet stairwell safety standards. Safety-spaced, coated metal bars create a sturdy barrier to protect little ones. Adjustment slots allow parents to customize width (between 29 1/2 and 44 inches) to individual needs. Great for hallways and doorways, too!
