A fiber distribution frame includes a housing and a door which opens and closes with respect to an exposed face of the housing to provide and restrict access to optic components within the housing. The frame further includes a door locking device having a door latch mounted to the door, a strapping post mounted to a side surface of the housing, and a cable connected at a first end to the strapping post. The door latch has a fastener receptacle and a cable conduit which adjoin one another such that a fastener received by the receptacle holds the cable in the conduit when the conduit receives a second end of the cable and the door is closed thereby locking the door to the housing. A diffuser component is attached to the inner surface of the door to absorb optical radiation from the optic components when the door is closed.
