Abstract
A protector for sheet metal coil is formed of plastic with a flange and sleeve which are joined together at a ridge portion. The protectors incorporate symmetrically disposed groupings of stacking features or components which include a finger within a stacking access opening, a stacking tab, and a stacking opening. The fingers are employed to resiliently engage the inner surface of a core of a coil and incorporate a receiver surface for freely abuttable engagement with a stacking tab of a second protector when arranged in mutual stacking relationship. The stacking openings function for stacking purposes to receive the protruding finger of a next stack protector.
