Scorpion II MASH Approved Attenuators

TrafFix Scorpion II attenuators are now available from Street Smart Rental. These are the first and only attenuators on the market that are MASH (Manual for Assessing Safety Hardware) tested and approved for use.

Scorpion II TMA


All Truck-Mounted Attenuators meet Test Level 3 NCHRP 350 approval and offer a wide range of protection for workers, motorists and equipment. Designed to absorb collision energy during rear-end impacts, the TMAs reduce expensive equipment damage and prevent impacting vehicles from under riding the truck.

Each system is constructed of a lightweight aluminum cartridge(s) with a reusable steel support frame. The truck system has a hydraulic system to lower and raise the TMA for storage.
