A deflector may be configured to reduce entry of at least one of dust or fluid into an enclosure configured to enclose in an interior thereof a plurality of optical communication connections. The deflector may include a first leg defining a first intersection edge and a first remote edge. The first leg may define a first hole adjacent the first end of the first leg and a second hole adjacent the second end of the first leg. The deflector may also include a second leg defining a second intersection edge and a second remote edge. The first intersection edge and the second intersection edge may be coupled to one another to define a deflector angle. The first hole may be configured to receive a first mounting stud associated with the enclosure, and the second hole may be configured to receive a second mounting stud associated with the enclosure.
