ABSTRACT:
A cover for rectangularily shaped grain boxes includes an essentially vertical extending circumscribing wall which mates with the walls of the grain box to thereby extend the volume and the depth of the grain box, an inclined roof surmounting the extending and circumscribing wall, and two hingeable lids attached to the roof which, in their closed position form a part of the roof, shielding the contents of the grain box from direct exposure to the elements, and while in the open position exposing the interior of the box.
