Traffic products

Our plastic traffic barriers double as traffic sign stands. They are safe, durable, and easy to handle. They come in two sizes: the lighter "Mörkö" for blocking narrow roads or for use as a traffic sing stand, and the heavier "Norsu" that can be chained together to form long barrier walls.
