A wiring duct assembly including a duct base and cover for supporting wire and/or optical cable therein, defining a latching mechanism located on both the cover and duct base. The latching mechanism on the duct portion includes an inwardly projecting sidewall portion, a lip attached thereto and a projecting tip potion integrally attached to the lip. The sidewall, lip and tip define a groove for receiving the latching mechanism of the cover. The cover includes two opposing side walls wherein each side wall includes an inwardly extending portion for being received by a corresponding duct groove. The latching mechanism for the cover portion further includes protuberances in the interior surface of the cover for securing the tip portion of the duct side wall to provide secure latching of the cover and duct base during shipping, installation, and completion of assembly.
