Abstract
A trapezoidal door and frame assembly and method of manufacture in which the assembly is constructed of a top horizontal frame member having the ends thereof arcuately shaped to conform with the radius of the upper corners of the cap. The ends are formed without deforming the flanges extending from the outer face of the frame member by removing, in a novel and unique method, portions of the flanges which permits cutting the ends of the frame member along a radius which matches the upper corners of the cap. This top door frame construction permits mounting the frame member closer to the top of the cap, thus providing a larger access opening and door in the rear of the cap.
