Abstract
An adjustable strap handle that can be used in connection with a packaging frame. The strap handle provides not only that the effective length of the strap is adjustable, but also provides that no tool needs to be used to install the strap. Additionally, a dual head self-pierce rivet is described that can be used in connection with a packaging frame, specifically to secure cardboard edge pieces to thin sheet metal or cardboard corner pieces and provide structure with which strap handles can engage. The dual head self-pierce rivet has a shank and a poke at its end. The poke is configured to pierce through the cardboard edge pieces of a cube frame, advance into the edge pieces, and flare into a profiled anvil. While a lower head of the rivet seats against the cardboard, an upper head contains and holds a strap handle in a ring groove.
