REACT 350®II Reusable Energy Absorbing Crash Terminal

The REACT350®II is a highly efficient, reusable crash cushion that features 6 High Molecular Weight/High Density Polyethylene (HMW/HDPE) cylinders attached to a steel base track. The system is NCHRP 350 Test Level 3 compliant as a redirective, non-gating crash cushion. The REACT II has proven self-restoring characteristics after being impacted at 62 mph by a 1,808 lb (820 kg) car, or by a 4,409 lb (2,000kg) pick-up truck. The REACT II can be used to shield narrow hazards of up to 3' (914mm) wide.
