An improved shelf bracket assembly has identical bracket members. Each bracket member is L-shaped and has a mounting portion forming one leg of the L and a flange portion forming the other portion. The mounting portion has a central raised section with an opening for receipt of a flange portion of the other bracket member. Each flange also includes a dimple and a cantilever finger. The dimple cooperates with the central raised section to maintain the bracket members in an intermediate prelocked condition. The cantilever finger cooperates with the central raised section to maintain the bracket members in a final locked condition.
