NCHRP 350 APPROVED

The SCI100GM is a fully redirective, non-gating, bidirectional Impact Attenuator. It was designed for safety and reusability. All required NCHRP 350 tests were performed with the same unit with no required replacement parts. To reset the SCI100GM after a frontal impact, you have to remove five pins, pull it out and replace the pins. Safety comes first with the SCI100GM as it provides lower average ridedown G forces due to the fact that it is a speed dependent system instead of fixed force. It requires minimal spare parts inventories due to the new side panel design which minimizes damage and snag potential on side impacts. During our testing, it produced very low angles of exit which reduces the potential of the vehicle rebounding back into traffic. Quick resetting due to minimal damage reduces worker exposure, repair part costs and repair labor costs.Crash / Impact Attenuator
