After rigorous testing by the Hammacher Schlemmer Institute, this pressure mounted pet gate was rated best for its sturdiness, pet restriction ability, and ease of use. The pet gate is made from fine hardwood with superior metal components and scored the highest for sturdiness because it remained stable when an 80-lb. dumbbell was hung from the top of the gate, while lesser gates could only support 30 to 50 lbs. It thwarted attempts by a 60-lb. Stafford Bull Terrier to climb over the top and prevented a slight, 10-lb. Bichon from escaping through the panels. The gate scored highest for ease of use because it is simple to set up; four tension springs adjust with the turn of a knob to fit door- or hallways from 28" to 36" wide; and the gate swings open--inward and outward--at the touch of a latch so you needn't struggle stepping over a gate or removing and replacing it every time you pass. The gate can remain as a permanent part of your decor, or be removed in seconds. Stoppers protect walls. Top is almost 35" tall. Imported. (20 lbs.)
