Modular shelving

A modular shelving assembly, comprising:

• at least three spaced poles, each having a connector, a first post unit and a second post unit, each post unit having first and second opposing ends, and a hollow interior that defines an interior surface, with a first protrusion extending radially inwardly from the interior surface of the first post unit adjacent the first end thereof, and a second protrusion extending radially inwardly from the interior surface of the second post unit adjacent the second end thereof, each post unit also having an outer surface;
• each connector having first and second opposing ends, a first track provided adjacent the first end of the connector and a second track provided adjacent the second end of the connector, each of the first and second tracks having a leg portion extending from one of the first or second end of the connector, and a foot extending from the leg portion, each connector further including a flange provided between the first and second track;
• icons provided on the outer surface of each post unit and the flange;
• wherein the first protrusion of each first post unit is retained in the foot of the first track of the corresponding connector, and the second protrusion of each second post unit is retained in the foot of the second track of the corresponding connector, when the first and second post units are connected to the corresponding connector;
• and
• wherein each leg portion has a first thickness, and one of the feet has a second thickness that is less than the first thickness of its corresponding leg portion.
