A flap barrier is an access control gate system that typically features retractable flaps made from glass, acrylic, or other durable materials. These flaps open and close to allow or restrict the passage of individuals. Flap barriers are commonly used in places where pedestrian access control is necessary, such as metro stations, office buildings, airports, and other high-traffic areas. https://www.novusapl.com/Flap-Barrier-Turnstile-NS-FS9-V210.php
