ABSTRACT:
A shelf system includes at least four posts and shelf members suspended from hooks which are arranged in rows and are cut out from the sides of the posts and are bent into the interior of the shelf system. Above the hooks but within the structural height of the shelf members, projections are formed in the sides of the posts for filling out the gaps between the edges at the ends of the shelf members and the sides of the post. Tongues are provided above the projections. The lower ends of the tongues are in alignment with the upper surfaces of the shelf members. When the tongues are bent upwardly, they secure the shelf members against being lifted out.
