Designed for permanent and workzone sites where impacts are expected more than 3 times per year or where traffic congestion and maintenance management is a concern for work crews.

The REACT 350 System features “smart plastic” cylinders made of high molecular weight, high-density polyethylene (HMW/HDPE) plastic. When impacted within the design capacity specified in NCHRP 350, they typically regain up to 90% of their original shape and capacity without maintenance or repair of major components. The REACT 350 System includes a range of units for design speeds from 72 km/h (45 mph) to 100 km/h (62 mph) and hazards up to 910 mm (36")

wide. REACT 350 Wide Systems are also available to protect hazards wider than 910 mm (36”).

The REACT 350 Impact attenuator features “smart plastic” cylinders made of HMW/HDPE plastic. When impacted within the design capacity of the system, the vehicle’s energy is absorbed by the cylinders and will then regain up to 90% of its original shape and capacity without the need to reset the system, allowing the system to take multiple design impacts without maintenance or repair to the system.

REACT 350® IMPACT ATTENUATOR

• Non-gating, redirective impact attenuator
• Performs effectively with design speeds up to 100 km/h (62 mph)
• Meets TL-1 (50 km/h / 30 mph), TL-2 (70 km/h / 43 mph) and TL-3 (100 km/h / 62 mph)

During head-on impacts, the REACT 350® impact attenuator crushes the reusable cylinders to absorb the energy of impact.

When impacted from the side, the REACT 350® impact attenuator redirects the errant vehicle back toward its original travel path without allowing gating.

Sectional design consists of energy-absorbing, reusable, "smart plastic" (HMW/HDPE) cylinders attached to a self-contained backup, or to a new or existing concrete-mounted backup system.

REACT 350® will self restore after most design impacts, typically regaining up to 99% of their original shape and capacity without maintenance or repair of major components.
