Abstract: A system of modular boxes as shown and described can be interconnected directly to one another via connectors that are integrally molded with the sidewalls of the boxes. The connectors of the boxes may include fastener receiving apertures for receiving a stud-mounting fastener therethrough. The connectors are thin and flexible, such that insertion and forcible tightening of a fastener through the aperture will cause a compressive force to be exerted between the interconnected boxes to maintain their spatial relationship and to maintain their interconnection. A further feature of the modular boxes of the system are anti-rotation members and receivers that are integrally molded to the side walls of the boxes. The anti-rotation members and receivers interact with one another at the point of connection between the boxes to prevent the boxes from flexing, rotating, or otherwise moving with respect to one another post-installation.
