The louver frame contains several louvers which permit one-way passage of the air to the exterior of the building. The louver frame is mounted to the vent duct attachment by means of tabs and a clip. The vent duct attachment is adapted to fit within a vent duct. The louvered cover may be mounted over a vent duct in a new construction, or, without use of the vent duct attachment, may be mounted over an existing vent duct cover.

  • Publication number: 20110312262
    Abstract: A pest guard vent cover may prevent the entry of large insects and animals into, but not obstruct the flow out of, the exhaust vent. A frame may have a rain guard, which terminates in pivot slots. A guard basket is pivotally and removably mounted within the pivot slots, so that it may pivot out and away from the frame for easy cleaning of dryer fluff. It may also be pivoted down towards the frame and attached to the frame by means of latches having angled flanges, which flanges catch the basket and releasably hold it against the frame.
