The 4F-TTM is a flared, single-sided, redirective/gating and energy-absorbing guardrail end terminal for use in roadside and shoulder installations to include approach or departure applications.
 
4F-TTM 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, 4F-TTM is designed to dissipate energy by engaging the energy-absorbing technology of the device. During length-of-need side impacts within MASH criteria, 4F-TTM is designed to contain and redirect the impacting vehicle.
 
Features:
Installed with a 4′ [1.22 m] flare to reduce nuisance impacts and length of barrier required to shield a hazard.
Only Post 1 has a 6′ [1.83 m] embedment.
During testing, debris field was significantly contained.
Shortest MASH tested Flared End Terminal.
Galvanized steel components reduce weather/UV-related issues.
The 4F-TTM utilizes a universal slotted TREND® 10 gauge W-beam panel at all locations.
ALL post spacings are 4’2″ [1.270 m] on center.
Connects directly to single-sided Midwest Guardrail Systems (“MGS”) W-beam.
