Product Description

The DEFLECT davha4/12 is a 4-inch aluminum vent hood accessory designed for residential and light commercial ventilation applications. This part fits within the Deflect-O line of duct accessories and service aids, providing a weather-resistant termination point for exhaust duct runs. The aluminum construction resists corrosion and holds up to outdoor exposure. HVAC technicians and installers use this fitting to cap vent runs at the building exterior, directing exhaust flow away from the structure while keeping out debris and backdrafts.

This vent hood is suited for 4-inch round duct systems commonly found in bathroom exhaust, kitchen range hood, dryer vent, and other low-pressure ventilation applications. It is a direct accessory replacement or new-installation component within the Deflect-O parts and accessories product family. Installation is straightforward and fits standard 4-inch duct collars used in residential construction and light commercial remodel work.
