REACT 350 attenuator passed safety tests as a self-restoring system that can sustain multiple vehicle hits without requiring repairs or resetting. During testing, the attenuator withstood three impacts: two by a 4,400-lb. pickup truck traveling at 62 mph, and the other by a small vehicle weighing 1,810 lbs. Meets TL-1, TL-2 and TL-3 requirements for stopping a vehicle traveling at 30, 43 or 62 mph, respectively. Contains high-density plastic cylinders that absorb vehicle impact, while regaining 90% of original shape and capacity to allow reuse. For secondary impact protection, cylinders attach to a self-contained backup system, as well as to new or existing concrete-mounted backup systems. Quixote Transportation Safety Inc., Chicago, Ill.
