MATT is a tangent, double-sided, redirective/gating and energy-absorbing attenuator/end terminal, for use with various longitudinal highway barriers in either unidirectional or bidirectional traffic applications – to include roadside, shoulder, median, and gore installations.
 
MATT is tested to MASH-2nd Edition (with 2020 Errata) Test Level 3 criteria and may be used in Test Level 1, Test Level 2, and Test Level 3 applications – when installed at the full Test Level 3 system length of 34′ 4-1/2″ [10.48 m].
 
During head-on impacts within MASH criteria, MATT is designed to dissipate energy by engaging the energy-absorbing technology of the device.
 
During length-of-need side impacts within MASH criteria, MATT is designed to contain and redirect the impacting vehicle.
 
Features:
Shortest MASH tested Median Terminal.
Galvanized steel components reduce weather/ UV related issues.
During testing, debris field was significantly contained.
Utilizes patented TREND® technology to absorb energy.
ALL post spacings are 6′ 3″ [1.905 m] on center.
Connects directly to double-sided Midwest Guardrail Systems (“MGS”) W-beam with 8″ (200 mm) blockouts.
Connection to double-sided Midwest Guardrail Systems (“MGS”) W-beam with 12″ (300 mm) blockouts can be achieved through the use of transition drawing SS6289.
Applications include Median, Roadside, Shoulder and Gore installations, for both approach and departure installations.
