Abstract: An all-plastic light duty shelf unit includes rectangular shelf modules and vertical spacers. Each shelf module has four corner joints that can either be mated directly with each other or coupled together using cylindrical vertical spacers. This allows the user to customize the configuration of the shelf unit to meet his or her specific needs. It also reduces the cost to manufacture the shelf unit because the vertical spacers can be extruded rather than injection-molded. The corner joints also hold a shelf off the floor, thereby reducing part count and manufacturing cost.
