ABSTRACT:
A protective sleeve for use with metal intake racks used for screening debris from water intakes and other similar structures. The proactive sleeve may be made from a plastic material, such as HDPE, using an extrusion process. The sleeve is designed to snap into place over the metal blades of a bar rack, and to provide a positive and secure fit when in place. The protective sleeve thus provides the benefits of non-metallic intake racks to existing and future metal rack systems, without requiring replacement of existing metal racks.
