Taller than the average safety gate at a full three feet high, Summer Infants Sure & Secure is the perfect solution for families with climbers. The fact that it only takes one hand to operate is also a blessing when youre arms are full of laundry, toys, or baby. To open it form either side (the gate is designed to swing both directions), simply slide the lever at the top of the gate with your thumb and then lift up. Closing doesnt require any hands at all: the gate will automatically shut and lock behind you, providing extra peace of mind.
