Abstract: A stake to support vertically positioned side panels on a flatbed trailer comprising a tubular member integral with a plate member, which, together with a T-shaped member, forms grooves to receive and support the side panels. The stake is reversibly received by pockets positioned at the periphery of the flatbed, and stakes are oppositely located along the sides of the flatbed such that their upper ends may receive the ends to tarpaulin bowed rods. The tubular member includes off center stop means to stop and support the ends of the tarpaulin bowed rods. Depending upon which end of the stake is seated in the pocket and the length of the end of the bowed rod used, the height of the transverse portion of the rod from the flatbed may be varied.
