Abstract: A weatherguard door sealing device comprising a single piece of metal with an outer leg, receiving leg, center section, first and second planar surfaces, first and second diagonal surfaces, and two inner reinforcing legs. The first planar surface connects the outer leg to the first diagonal surface, the first diagonal surface connects the center section to the first planar surface, the second planar surface connects the receiver leg to the second diagonal surface, and the second diagonal surface connects the center section to the second planar surface. The receiver leg comprises a receiver channel for receiving a sealing element. The two inner reinforcing legs are parallel to each other and extend perpendicularly from the center section. The thickness of the center section is greater than the thickness of the first and second planar surfaces and the first and second diagonal surfaces.
