Abstract
Abstract A storage rack assembly including a post of sheet metal or the like having at least one supporting wall with a front face and a back face. A plurality of slots are formed in the supporting wall and are spaced from each other along the length of the post. A beam of sheet metal or the like has a web portion with a front face and a pair of load carrying tabs struck from the front face and spaced from each other in a direction transverse to the length of the beam. Each of the load carrying tabs are received in one of the slots in the post such that the beam extends transversely of the post. A projection is struck from the front face of the beam and engages an edge of the supporting face so that the beam is firmly secured against horizontal movement with respect to the post. An anti-lift tab is provided on the beam to project through one of the slots to firmly secure the beam against vertical movement with respect to the post.
