A vent unit that can be fitted to a vehicle rear door by closing a window onto the device allows secure air circulation for pets whilst keeping out rain and insects. The unit is made of 3 sections: an inner section (fig 1) with vent holes 2, a middle section (fig 2) with metal fly screens 4, and an outer section (fig 3) with rain deflecting grilles 3. The unit has a tongue on the top and a groove on the bottom, and the sections can be plastic or metal glued together to form the unit. |
