ABSTRACT:
In a sheet metal shelving system, shelf clips for retaining shelves on support posts are provided with hooks for engaging openings in the support posts and also with projections which enter openings and prevent removal of the clips from the posts. The projection is held in place in its opening by reason of the engagement of a shelf apron in the retaining portion of the clip. The apron is held in the retaining portion of the clip by a snap-fit relationship between a rolled lower edge of the apron and one or more projections formed in the retaining portion of the clip.
