Roadbloc™ Traffic Separators The RoadBloc™ from JSP has been manufactured from Solathene™ HD and the system has been extensively trialled to ensure that it surpasses the demands and expectations bestowed on Traffic Separators by today's Traffic Management industry. It's unique hinge allows it to form a mini roundabout with just eight units and to bend upwards so that they can stand firm on uneven ground. They can also be stacked very conveniently. Stacks of 16 RoadBloc™ supplied securely banded. Roadbloc™ can be water-filled for extra stability. Mini Roundabout Each barrier can swivel at its connection point up to 45° to enable 8 systems to form a circle. Uneven Terrain Each unit can be tilted at an angle whilst still connected making it ideal for use across uneven terrain. Visibility Reflective strips can be placed to sit within a recessed area on each unit. There is also the option to add 1M high PVC barrier boards supported on 60mm diameter poles for increased visibility.
