The Sentry Barrier TL-4 ThrieBeam System is a roadside Thrie-beam guardrail system suitable for containing, redirecting and shielding vehicles from roadside obstacles. The barrier has been designed and tested to meet the evaluation criteria of MASH Test Level 4 for a longitudinal barrier. This is the current and highest performance testing criteria in line with AS/NZS 3845.1:2015, exceeding the requirements of NCHRP 350 Test Level 4.
