The connector web may also define an outer surface (118) and an inner surface (120). The slat may also include a front wall (122) extending outwardly from the outer surface of the connector web along the front side of the slat and a rear wall (124) extending outwardly from the outer surface of the connector web along the rear side of the slat. Additionally, the slat may include one or more additional features for increasing the structural integrity of the slat and/or for enhancing the crop grabbing/gripping capabilities of the slat.
