DTB 2N (1 way with double-sided structure and closed anchor) is recommended for highways and conventional roads with high winter traffic. Due to the pressure with which the snow impacts on the reflector when the snow blower passes, the robustness offered by the structure of a DTB 2 with the functionality of a DTB 1 is necessary so that the reflector does not bend.
