Abstract
In a storage rack comprising a front beam, a back beam, and a crossbar extending therebetween, the front beam having a vertical wall facing backwardly and a horizontal ledge extending backwardly, the back beam having a recess wall facing frontwardly and a recess ledge extending frontwardly, a first slot is provided in one such wall and a second slot is provided in the other wall. The crossbar has a first tang extending from a first end and adapted to be initially inserted into the first slot and a second tang extending from a second end and adapted to be subsequently inserted into the second slot without removing the first tang from the first slot. Each end can sit firmly on a beam ledge with the tangs extending into the slots. The tangs have notches providing clearance for slot margins and end tabs preventing the tangs from being pulled out.
