Trailer Gap Devices

Tractor-to-trailer gap management devices, commonly called nose cones, are mounted to the front of the trailer, generally near the top, to limit the air gap between the tractor and the trailer. These devices are ranked third in adoption priority. They are best suited for use with day cabs, mid-roof sleepers, and older styled conventional tractors.

Another type of trailer gap device uses the natural tendency for air to swirl in the tractor/trailer gap. They are designed to help maintain these vortices.
