The side plate includes a tail section proximate to the rear of the side plate, a midsection between the front plate and the tail section, and at least a portion of the tail section has a height larger than the midsection to thereby define a gap above the midsection. A brush is mounted on at least the midsection. The brush includes plurality of bristles extending from the brush such that the end of the bristles are substantially collinear with a top of the at least of portion of the tail section, to thereby substantially cover the gap.
