Stanchions are upright posts or poles used to create barriers or guide people in a specific direction. They are often connected by ropes or chains and are commonly found in places like airports, museums, and event venues to manage crowds and organize lines. These structures can be made from various materials, including metal, plastic, or wood, and come in different designs and colors. Stanchions are useful for maintaining order during busy events and ensuring safety by directing foot traffic away from restricted areas.
