H Class Mill Chains

H Class Mill Chains are cast of high grade malleable iron, and are used primarily for drag conveyor service in the lumber, pulp and paper industries. They are also desirable for transfer and conveying purposes. The closed pin joint permits operation in a moderately dusty or abrasive atmosphere. A wide range of attachments are available for conveyor service.
