Abstract: One embodiment of the present device includes a perimetrical shield or flashing secured between the lower edge of the wall and the conventional outwardly facing angle iron base secured to the floor. Shield is bolted or riveted between the wall and the angle iron and extends over and preferably slightly below the lower perimetrical edge of the floor of the bin. Another embodiment includes the shield situated between the wall and an inwardly facing perimetrical angle iron which is easy to manufacture and is less likely to provide moisture ingress. A further embodiment includes the shield being formed as an extension of the wall and being shaped to extend over and slightly below the perimetrical edge of the floor and to be bolted either to the floor or to the angle iron.
