Work Zone Drums & Barricades
Work zone devices are read at close range and low angle — Type IV is the volume answer.
Read at close range and low angle — Type IV is the volume answer. A drum or barricade is hit, dropped, pressure-washed and put back out the same week — the film has to survive that and still return light to a driver who is nearly on top of it.
NVR-4200 is high-intensity prismatic Type IV, supplied by the roll or pre-cut to the drum panel size. It is the grade most of our work-zone customers reorder because the next grade up buys brightness nobody sees at 10 m.
NVR-CN70 cones and NVR-DP90 delineator posts usually travel in the same container, so the whole device set arrives with one packing list and one acceptance document set.

Highway & Expressway Signs
Overhead gantry panels read at a wide observation angle — the case for Type VIII / Type XI, not Type IV.
Delineation & Guideposts
A delineator is a small target repeated at speed — Type II is enough and lasts seven years.
Tunnels & Underpasses
Tunnel signage is lit by headlights against a dark surround — Type XI plus a passive photoluminescent fallback.
