Overhead door header with maximum clearance

A truck trailer comprising:

• first and second sidewalls;
• an overhead door assembly including a door opening and at least one door panel moveable between an open position and a closed position;
• first and second foot angles positioned at upper corners of the door opening;
• a counterbalance assembly configured to aid in moving the at least one door panel between an open position and a closed position, the counterbalance assembly being supported by a shaft;
• and
• a header at a rear end of the truck trailer, the header enclosing the counterbalance assembly and including:
• a top surface,
• a rear surface coupled to a rear end of the top surface,
• a bottom surface coupled to a bottom end of the rear surface,
• first and second reinforcement members disposed between the rear end of the truck trailer and the counterbalance assembly and forward of the rear surface, the first and second reinforcement members being coupled to one of the first and second sidewalls, respectively, and at least one of the top surface or the bottom surface, the first and second reinforcement members being substantially parallel to the rear surface and each extending transversely from one of the first and second sidewalls, past an inner end of one of the first and second foot angles, toward a center of the header and each terminating short of the center of the header, and
• first and second shaft support members coupled to and spaced inwardly from ends of the bottom surface and substantially perpendicular to the rear surface, first and second ends of the shaft being coupled to the first and second shaft support members, respectively.

A header for enclosing a counterbalance assembly for use with an overhead door assembly of a truck trailer, the header comprising:

• a top surface;
• a rear surface coupled to a rear end of the top surface and configured to be positioned adjacent an upper rear wall of the truck trailer above a door opening of the truck trailer;
• a bottom surface coupled to a bottom end of the rear surface;
• and
• at least one reinforcement member disposed rearward of the counterbalance assembly and forward of the rear surface and being coupled to a sidewall of the header and at least one of the top surface or the bottom surface, the at least one reinforcement member providing reinforcement to the header by extending from the sidewall of the header past an inner end of a foot angle positioned in a corner of the door opening and terminating short of a center of the header.
