Abstract: A deflector plate support includes a support body having an integral frame-like construction and a first end portion and a second end portion each of which are connected to a perpendicularly disposed border that is connected to an inwardly extending wall disposed perpendicular to the border. Each end portion of the support body, each border, and each inwardly extending wall are joined to a base at a common end thereof to thereby define, in association with the support body, a slot for vertically or horizontally receiving, releasably retaining, and orientating the deflector plate such as to expose a front deflection surface or a plurality of front deflection surfaces of the deflection plate.
