Abstract: A cover for a round, kettle type barbecue grill, generally dome shaped, adapted for use with a correspondingly shaped, round grill base. It is generally closed, having a relatively stationary fixed back section and a hinged front section forming a door, movable between an open position, exposing the interior of the grill, and a closed position, entirely closing the grill. Even in open position, the cover forms a windbreak and shields the food in the grill from the wind. The cover is designed to be rotatable on the base, so as to position it according to any direction of the wind. In one form, the door extends to and through the bottom edge of the cover, and in another, it terminates short of that edge, and the stationary back section is continuous around its bottom edge, extending below the door. The cover can be put out as a separate item, or as part of a complete grill. It is also well adapted to be put out in different sizes.
