  • Aerodynamic rear drag reduction system for a trailer
    Patent number: 9616944
    Abstract: A rear aerodynamic drag reduction system is configured to be coupled to a rear frame assembly of a trailer including a rear frame and a rear swing door. The rear drag reduction system includes a main wall panel configured to be coupled to the rear frame assembly to extend generally rearwardly of the trailer at least partially along a height of the trailer, and a secondary wall panel configured to be movably coupled to the rear swing door of the trailer to extend along a width of the trailer. The main wall panel and the secondary wall panel are each movable relative to the rear frame assembly between a deployed position and a stowed position. A locking mechanism of the drag reduction system is configured to releasably couple the main wall panel and the secondary wall panel to each other to prevent relative movement between the main wall panel and the secondary wall panel when the main and secondary wall panels are in their deployed positions.

  • Butt joint for trailer side wall
    Patent number: 8424958
    Abstract: A butt joint assembles side panels of a trailer to the base rail of the trailer to form a side wall. The butt joint positions the side panels over the base rail and vertically aligns the outer surfaces of the side panels and the base rail, which provides for an improved trailer side wall.
