Abstract: A perimeter fence comprises at least one substantially horizontal base portion and at least one corresponding barrier portion, which is removably secured to the respective base portion, comprising a pair of substantially vertical posts and a panel supported therebetween. The fence limits access to a designated area and can be used, for example, for crowd control at concerts and other outdoor events, protest/demonstration crowd management and facility/infrastructure perimeter protection. The fence utilizes a modular design and an improved fastening and storage system; and thus can be readily assembled for mobile use and disassembled for storage and transport. Metal expanded wire mesh or solid panels are provided to maximize security and limit access. The fence is provided in various dimensions to reduce scalability and thus further limit access. A plurality of adjacent panels can be employed to extend the fence as necessary about the designated area based on the particular application.
