Traffic barricade and traffic cone accessories extend the use of barricades and cones and keep them in good working order. Beams, bars, panels, and belts block traffic and direct it away from hazards. Lights draw attention to cones and barricades. Bases, weights, and barricade feet and legs ensure cones and barricades remain upright. Signs and cone collars communicate safety messages to pedestrians and drivers. Cone holders, carts, and storage bags help organize and store cones when not in use.
