Abstract
A control barrier is provided having a barrier wall with one or two support assemblies attached thereto. The barrier wall has a front face with a display recess, wind ports, and tenons and mortises formed thereon. The barrier wall also has a set of projecting arms having either pins or ports to allow a series of control barriers to be connected together. The support assemblies are positionable between a support position and a standing position. Preferably, the support assemblies include a leg and a foot. The leg is extendable and/or rotatable to allow the foot to be positioned between a support position and a standing position.
