Abstract: A dunnage holder constructed by a vertically oriented steel tube that has a generally hollow rectangular cross-section adapted for inserting into a stake hole around an outer rail of a flatbed trailer, the steel tube that has a length of at least 3-inches; and a U-shaped steel channel permanently attached by straddling in an inverted position to a top of the steel tube, the U-shaped steel channel that has an opening sufficiently large to receive a first end of a 4-inch by 4-inch wooden brace therein and to dispose the wooden brace across a full width of a flatbed of the trailer when a second end of the wooden brace is received by a corresponding, oppositely positioned U-shaped steel channel on an opposite end of the flatbed.
