The Safeway Gate is rated number one for the top of the stairs by a leading independent consumer organization. Constructed of sturdy, tubular steel with a non-toxic coating, it mounts permanently for added safety. It's easy to install and easy to remove, and the one-hand operation makes it easy to use, too. An exclusive, easily adjustable feature prevents the gate from swinging open over the stairs. It fits openings from 24.75" to 43.5" wide, and also works with most railings and angled walls. Measures 30.5 inches high.
