AT&T Stadium

Operable End Zone Walls

The two operable end-zone walls at AT&T Stadium are the largest in the world, measuring 120 feet high by 180 feet wide. Each wall is is made of five 38-foot wide, 5-foot thick glass-clad panels that open or close in 18 minutes. The clear glass cladding allows for  panoramic views from within the stadium when the walls are closed. The walls are opened to promote air circulation and to allow stadium visitors to move freely between indoor and outdoor public areas. The open end zone walls, along with the open retractable roof, give visitors an outdoor stadium experience when weather is favorable.

The staff of Uni-Systems Engineering designed, supplied, and installed the structures and electro-mechanical drive systems for the AT&T operable end zone walls. Each panel is driven along rails embedded in concrete by two traction drive wheels each powered by an electric motor. Guide rollers mounted to the top of each panel move along tracks mounted above the wall opening.

Uni-Systems Engineering staff also designed, supplied, and installed the retractable roof, video board mechanization, and arch pin connection at AT&T Stadium.
