This traffic control bollard set with chain is specially designed to identify hazards or designate off-limit areas on the road and effectively reduce traffic jams. The bollard posts are made of PE, which makes them lightweight and easy to move around. They form a highly visible barrier to guide or restrict access. The posts have reflective silver stripes to make drivers more aware of them, even in the dark. With the included top connector and chain, posts can be easily connected to each other.
