Abstract: A coupler for coupling two posts end-to-end has ninety degree flanges and two reverse wrap ends. The coupler is slid one-half way over the ends of one formed post, comprising two flanges, with the reverse wrap holding the post flanges. Another flanged post is inserted into the coupler to engage the end of the first post, the coupler holding the posts end-to-end. An alternate embodiment coupler is disclosed.

Abstract: A storage receptacle is provided that has first and second sides and a bottom made as a unitary member from a single piece of sheet metal. The receptacle also includes front and rear ends, each coupled to the two sides and providing support for the bottom.

Abstract: A connector is provided for securing two members together. The connector includes an opening formed in one member and a tab extending from the other member. Either the opening or the tab is tapered for frictional engagement with the other when the members are joined.

Abstract: A cargo rack utilizing structural beams, structural beams used in a framework comprising a plurality of vertical posts with either key shaped apertures or slots and a plurality of horizontal shelving members, structural beams contain either circular apertures when corresponding vertical post contains key shaped apertures or fingers when corresponding vertical post contains slots enabling structural beams to connect to vertical posts, thus allowing horizontal shelving members to be associated with structural beams and vertical posts.

Abstract: A cargo rack utilizing a structural beam in the form of three embodiments, two of the embodiments comprising a rib, one of which includes a recessed flange and a horizontal return flange, the other includes a standard angled flange and an angled return flange, the third embodiment includes a recessed flange and a horizontal return flange, structural beams used in a framework comprising a plurality of vertical posts containing key shaped apertures and a plurality of horizontal shelving members, structural beams contain nubs enabling structural beams to connect to vertical posts via key shaped apertures thereby enabling horizontal shelving members to be associated with structural beams and vertical posts, various attachments may be added to cargo rack when recessed structural beams are used via a slight clearance that is formed between the recessed edge and a slight taper on horizontal shelving member sides.
