International ClassE01F 009/06AbstractA modular barrier for attachment to a barricade along a road side for substantially blocking vision toward construction zones or other areas of distracting activity. The barrier includes an elongated base plate with attached support posts which include mounting tracks for insertion of opaque panel members between adjacent posts. Panel edges are configured for tongue-in-groove insertion within channel tracks formed at the lateral sides of each support post. The modular construction of this unit enables quick and economical emplacement at construction areas and other sites where vehicle drivers are prone to distraction by off road activities. | |
