The louvered design allows air to pass through while helping to block backflow when the connected fan or blower is not running. This type of cover plate is a standard component in residential and light commercial ventilation installations, including dryer vents, bathroom exhaust fans, kitchen range hoods, and general HVAC duct terminations. Installation is typically handled by HVAC technicians, sheet metal contractors, or plumbers completing ventilation rough-ins.\u003c\/p\u003e\n\u003cp\u003eThe 2677B is suited for 4-inch round duct systems commonly found in residential exhaust ventilation applications.
