DoT Notes on A-Frames

"If your towed car has vacuum assisted power brakes
it is likely that this assistance will be required while in motion
to meet the legally required braking efficiencies"

Intelligent Towed-Vehicle Braking

Smart-Tow Vacuum-Assisted Braking System makes towing a vehicle safer and easier with state of the art braking products. There are many braking systems available today, but we are sure you will see the difference SmartBoxDUO makes.

SmartBoxDUO is the only dual-sensing, vacuum-based system. By using the car's own power brakes, pedal pressure is reduced to only 10 pounds in normal stopping. We are also the ONLY Vacuum-Assisted system that maintains the level of vacuum in the system to provide consistent braking from your towed vehicle.

SmartBoxDUO Vacuum-Assisted Braking Systems are more efficient, easier to install, and costs less than other braking systems and we can provide you with a Declaration of Conformity for your peace of mind
