Turnstile gate barriers
Turnstile gate barriers are mechanical or electronic devices used to control pedestrian access to a particular area. They are often seen in places like stadiums, train stations, office buildings, and amusement parks. Turnstiles consist of vertical posts with horizontal arms or bars that rotate to allow or restrict passage.
Controlled Entry: Turnstiles provide controlled entry by allowing only one person to pass through at a time. This helps manage pedestrian flow and ensures that only authorized individuals gain access to a specific area.
Direction Control: Turnstiles can be configured to allow passage in one direction only (e.g., entry-only or exit-only) or in both directions, depending on the needs of the location.
