ATDynamics says its new RollTail, rear-mounted aerodynamic fairing is the first commercially available tail fairing specifically designed for trailers with roll doors.
Previous TrailerTail designs have been for swing-door design trailers.
The new RollTail is a DOT-compliant, spring-actuated fairing that can be installed by two technicians in as little as 45 minutes. The unit requires no driver interaction when backing into a loading dock as the unit retracts and deploys automatically when the vehicle pulls away.
The company says the RollTail will improve tractor-trailer fuel economy by 4 to 5 percent, and has been validated by SAE Type II fuel economy testing. The product weighs approximately 160 pounds and will retail for $1,599.00.
