Modular Storage Unit Including Sub-Units

A storage device comprising:

• a housing defining a front surface and an opposing rear surface;
• a plurality of male couplers extending from the rear surface, each of the male couplers are configured for arresting engagement with an upper surface of a first utility module, the plurality of male couplers each comprising a body extending from the rear surface, a first tongue, and a second tongue, the first tongue and the second tongue both extending from the body and both offset from and above the rear surface, the first tongue defining a first channel between the rear surface and the first tongue, the second tongue defining a second channel between the rear surface and the second tongue, the first channel and second channel each extending on opposing sides of the body, each channel comprising a front open end and a back closed end;
• a plurality of containers each defining a storage compartment, the plurality of containers each slidably coupled to the housing, wherein when the plurality of containers are positioned in an extended position, at least 50% of an upper opening of the respective container is positioned in front of the front surface of the housing;
• and
• a locking mechanism coupled to the housing, the locking mechanism configured to secure the plurality of containers within the housing when the locking mechanism is arranged in a locked configuration.

A storage device comprising:

• a housing defining a front surface and an opposing rear surface;
