For roll-up doors — Like the Wake Board, the
Frame Extension reduces the wake of the trailer and increases base
pressure to reduce drag. The Silver Eagle Frame Extension is a structural
extension of the trailer frame, able to stand up to all that happens
in this area — docking, forklift traffic and all. This technology
has undergone extensive wind tunnel testing and will provide 4 to 5
percent fuel savings.
