Safe-Stop TMA® Truck Mounted Attenuator Model #8291

Products / T.M.A. / Safe Stop TMA Model #8291

  • Meets NCHRP 350 TL-3 criteria for 100 km/h (62 mph) TMA for design impacts
  • Was subjected to all four mandatory and optional tests recommended in the NCHRP 350 report
  • The Safe-Stop TMA is only 3.98 m (13'2") long yet it protects against high-speed impacts.
Superior Design
  • Two light-weight aluminum cartridges are contained in a reusable steel support frame. When impacted, the steel support frame collapses and the aluminum cartridges crush to absorb the energy of the impact, bring the vehicle to a safe, controlled stop and prevent it from underriding the truck.
Fast and Easy Refurbishment
  • After a typical design impact, the steel support frame and strike plate are reusable, and only the two aluminum Safe-Stop cartridges need to be replaced. Refurbishment can often be done in the field.
