ABSTRACT:
In one embodiment, a port cover for a system integrated into a structure for injection of a material into one or more cavities in the structure includes a base for coupling to the structure. The base includes one or more ports for injection of the material into the one or more cavities in the structure and one or more slots. The port cover also includes a cover for removably coupling to the base, the cover including one or more tabs each adapted to engage with a corresponding slot of the base. The cover also includes a locking mechanism for removably securing the cover to the base to prevent unauthorized access to the one or more ports. The locking mechanism is adapted to engage a projection of the base to removably secure the one or more tabs of the cover in engagement with the one or more corresponding slots of the base to removably secure the cover to the base to prevent unauthorized access to the one or more ports.
