The X-TENSION 350 Median Guardrail End Terminal has been designed and tested to meet the evaluation criteria of NCHRP 350 Test Level 3 (TL-3). The system has been tested to the guidelines in NCHRP 350 for a non-gating, re-directive guardrail end treatment. When correctly installed and maintained, the system is capable of stopping, containing, or redirecting an errant vehicle in a safe manner under NCHRP 350 impact conditions.
The X-TENSION 350 Median Guardrail End Terminal is a fully re-directive, non-gating guardrail terminal end. The unique X-TENSION 350 Median technology is a tension based solution rather than compression based. It offers exceptional vehicle control and energy absorbing capabilities in head on impacts, where the energy is absorbed with resistance at the impact head rather than being transferred down the rail as occurs with other systems. Even head on, high angle (15° during testing) impacts on the nose resulted in the vehicle being redirected and controlled.
