It features a built-in screen to block pests and debris, a spring-loaded damper that opens under airflow and closes when the system is off, and a gasket for a weather-tight seal at the wall penetration. The aluminum body resists corrosion and holds up in exterior applications where steel fittings would deteriorate. This vent is a direct-mount termination cap intended for duct runs requiring a 4-inch wall outlet.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for exhaust duct terminations serving bathroom fans, kitchen range hoods, dryer vents, and similar mechanical ventilation equipment in residential and light commercial buildings. It mounts flush to the exterior wall surface and accepts a 4-inch round duct collar. Contractors and installers use it where a low-profile hooded cap with integral backdraft control is needed at the wall face.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch round duct connection for standard residential exhaust applications\u003c\/li\u003e\n  \u003cli\u003eSpring-loaded damper closes automatically when airflow stops, limiting backdraft and heat loss\u003c\/li\u003e\n  \u003cli\u003eBuilt-in screen blocks birds, rodents, and insects from entering the duct\u003c\/li\u003e\n  \u003cli\u003eGasket provides a weather-resistant seal between the cap and the exterior wall\u003c\/li\u003e\n  \u003cli\u003eAluminum construction resists corrosion in exterior and high-humidity environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style termination cap for 4-inch round exhaust duct systems in residential and light commercial mechanical ventilation installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by HVAC technicians or general contractors during rough-in or finish work.
