|May-Wes Auger Liner covers the full length of the floor under the auger — not just the feed opening. First designed for grain heads, it is also available for corn heads. Condensation and wet grain or corn will not corrode poly lining when the metal is covered with poly. Even when metal lining is corroded, the poly lining keeps loose grain from falling through rust holes. Poly lining is much easier to replace than factory metal. Simply bolt and rivet into place. Please specify exact width when ordering.
