A thrust reverser blocker door may comprise a proximal surface, a distal surface located opposite the proximal surface, a first attachment feature extending from the distal surface, a second attachment feature extending from the distal surface, a drag link housing extending from the distal surface, a first diagonal stiffener extending from the distal surface and extending between the first attachment feature and the drag link housing, a second diagonal stiffener extending from the distal surface and extending between the second attachment feature and the drag link housing, a first perimetrical stiffener extending from the distal surface and extending from the first attachment feature and the drag link housing, a second perimetrical stiffener extending from the distal surface and extending from the second attachment feature and the drag link housing, and a middle stiffener extending between the first attachment feature and the second attachment feature.
