Abstract
An aerator pad for a railroad hopper car has a fabric body member that overlies an aeration assembly slope sheet. The body member has a perimeter portion with indentations formed in the edges thereof. A gasket is molded to the perimeter of the body member. Bolt holes in the gasket are spaced from the fabric so that no edge or perimeter portion of the fabric is exposed to atmosphere. The gasket is located between mating flanges of the aeration assembly and car body. Spacer buttons lift the body member off the slope sheet and a wear pad prevents vibration induced deterioration at the gas inlet opening in the slope sheet.
