Abstract: A shelf support beam for use in a shelving unit to support a shelf. The support beam includes a first end and a second end located at opposite longitudinal ends of the shelf support beam between which a structural member extends. The structural member has a C-shaped cross-section and includes a web separating a top flange that is configured to support the shelf from a bottom flange. The support beam further includes a tab located at each of the first and second ends of the structural member. Each tab includes a pair of securing fingers that are angled relative to a plane disposed perpendicular to a longitudinal axis of the shelf support beam such that each securing finger is angled inwardly toward a center of the structural member. The support beam further includes an enforcement tab formed in the web at each of the first and second ends of the structural member.
