The wider clear opening allows more people to pass through at the same time, helping increase evacuation speed and reduce crowding, pushing, and bottlenecks. Both door leaves are equipped with UL-certified panic push bars, allowing occupants to open the doors quickly and easily with a simple push during an emergency.
