The ACP Sentry Median Barrier W Beam System is a roadside w-beam median guardrail system suitable for containing, redirecting and shielding vehicles from roadside obstacles.                           
The Sentry Median Barrier is a double-sided W-beam rail back to back on a single post.  This system is designed to be impacted from either side, where contra-flow traffic needs to be separated.  The median barrier is used where there is a median strip between lanes of traffic.                                                                                  

The barrier has been designed and tested to meet the evaluation criteria of MASH Test Level 3 for a longitudinal barrier. This is the current state of the art performance criteria, exceeding the requirements of NCHRP 350 Test Level 3.

• MASH Test Level 3 compliant as a permanent Longitudinal Median Barrier system

• AS3845:2015 compliant

• Lesser components, weight and footprint than conventional public domain guardrail systemsLesser components, weight and footprint than conventional public domain guardrail systems

• Superior dynamic deflection results compared to public domain systemsSuperior dynamic deflection results compared to public domain systems

• Conventional ‘C’ shaped post but shorter, smaller and lighter then public domain versions

• No block out, stiffener or bracket between rail and post connectionNo block out, stiffener or bracket between rail and post connection

• Large flexibility and tolerance in system height to accommodate easy transitioningLarge flexibility and tolerance in system height to accommodate easy transitioning

• Designed for use with an X-Tensional 350 Median End Terminal
