Verdegro's The BLADE™ Trailer Mounted Attenuator (TTMA)

Arrow board and foil chevrons sold separately.

Protect your workers with the safest, most innovative and highest safety level, trailer truck mounted attenuator available. The BLADE™ Trailer Mounted Attenuator safely protects and redirects the impacting vehicle away from the "coffin corner" area at the rear of the truck. 


The TMA's strength comes from the composite aluminum welded profiles with 12 internal blades. During an impact, the first 4 blades cut through the aluminum composite H-beams and, after unlocking, 8 blades cut through the welded tubes. The remaining weak aluminum parts will bend away in safe directions. The patent is based on cutting aluminum H beams and tubes using BLADES.
