Testing criteria for highway roadside hardware have been in place since 1962. NCHRP Report 350, Recommended Procedures for the Safety Performance Evaluation of Highway Features, has been the accepted method for safety hardware device testing and eligibility since 1993. In 2016, FHWA announced a new protocol for crash-testing safety hardware devices: The American Association of State Highway and Transportation OfficialsManual for Assessing Safety Hardware (MASH). Among other changes designed to better reflect potential damage from the generally larger and higher vehicles on the nation’s streets and roads are standards affecting truck-mounted attenuators (TMAs).

The Blade passed this standard in testing conducted by the Texas Transportation Institute. The TMA consists of composite aluminum welded profiles and 12 internal blades. At impact, the first four blades cut through the aluminum composite H-beams and, after unlocking, the remaining eight blades cut through the welded tubes. The remaining weak aluminum parts bend away.

The Blade comes with a quick-connect and level system so the attachment can be quickly installed and removed and adjusted to be perfectly horizontal. Accessories include arrow board bracket, truck bracket, foil, jockey wheels, and truck bodies.
