The housing assembly includes a front plate and a back plate in which the insert is disposed the front and back plates. The insert attaches to the back plate to prevent animals from entering an exhaust vent. However, the insert lacks a fluid diverter to divert a fluid away from a wall of a building.
Therefore, there remains a need to develop a housing assembly having a locking device for selectively coupling and uncoupling an insert with a fluid diverter.
SUMMARY OF THE INVENTION AND ADVANTAGES
The present invention provides for a housing assembly to mount to a wall of a building. The housing assembly includes a front plate attached to a back plate. The back plate defines an axis and includes a flange extending radially away from the axis for coupling to the wall. An insert is disposed between the front plate and the back plate. The insert includes a central body having a fluid diverter extending outwardly from the central body for redirecting a fluid away from the wall of the building.
