Description

Crowd control barriers act as a physical and psychological barrier, used to demarcate “no access” zones, and to designate space for lines. They are also used by riot police to control large gatherings.Crowd control barricades are most commonly made of steel, although lighter-weight plastic variations are sometimes used. Barriers are most effective when they interlock, being attached to each other in a line via hooks at the side of each barricade. When barricades are interlocked, security personnel can create impenetrable lines, because such lines of barriers cannot easily be toppled over.
