mutually perpendicular height, width, and depth;

a first sidewall delimited by the height and the width and having a bottom adjacent a bottom of the seal and a top adjacent a top of the seal;

a second sidewall extending from the first sidewall, the second sidewall delimited by the height and the depth, the second sidewall including:

a longitudinal portion;

a lateral portion extending from the longitudinal portion; and

at least one aperture configured to receive a fastener for attaching the seal to a bottom corner of the overhead door, the at least one aperture having a length providing a tolerance for the seal to move relative to the overhead door and the fastener;

wherein the first sidewall is tapered from the bottom of the first sidewall to the top of the first sidewall, wherein the bottom of the first sidewall has a first thickness along the depth and the top of the first sidewall has a second thickness along the depth, wherein the first thickness is greater than the second thickness, and wherein the first sidewall, in vertical cross-section, has a triangular shape.
