Flap barriers are types of pedestrian access control systems commonly found in various settings such as train stations, subway stations, airports, office buildings, and other secure areas. They consist of motorized barriers that allow only one person to pass through at a time. These barriers typically have retractable flaps or panels that open and close to allow or restrict passage. https://www.novusapl.com/flapbarrier-ultrapremium-series.php
