Abstract: A connector having a plurality of prongs at each end. The prongs can be inserted into portals, such as those of slat board. The connector can be locked in place by angling the prongs into the portals and connecting two parts of the connector to each other, such as by a male and female connector, which lock and affix in place, requiring a tool to remove. A connector arm can also be attached to the connector, extending outwards, such as at an acute angle, to the connector. On this arm, an extension arm can be further attached. Either the connecting arm or extension arm can have portals for a hook or an integrated hook from which merchandise can be hung. Each of the connecting arm, connector, and extension arm can be reversibly or removably attached one to the other by way of a depressible button on one device extending through a portal of another.
