These racks are made of a steel frame fitted with a sewn bag assembly. Bags are made of high performance vinyl material. For class A surfaces, Tvyek and headliner fabric is used. For parts with sharp edges, HDPE is used. Foam padding is often used to secure parts in a certain orientation. Eisen manufactures grid, nested, and honey comb bags to achieve highest density of parts per rack. Collapsible racks are available for clients that have fleets travelling long distances. This reduces cost drastically on return trips. Contact your sales representative to review your packaging needs.
