Built to the R-2 Pro specification, it features a powder-coated finish for corrosion resistance and long-term exterior durability. The cap includes an integrated damper to prevent back-drafting and an animal screen to block pests and debris from entering the ductwork. Licensed HVAC technicians and sheet metal contractors install this cap as the termination point for 4-inch round duct runs that exhaust through roof penetrations.\u003c\/p\u003e\u003cp\u003eThis vent cap is suited for residential and light commercial ventilation systems where a roof termination is required. Typical applications include bathroom exhaust fans, range hood vents, and similar low-pressure exhaust duct systems that terminate through the roof deck. The heavy-duty construction makes it appropriate for installations exposed to weather, UV, and mechanical wear. It is sold in a package quantity of 3 units, making it practical for multi-unit or multi-room projects.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch round duct connection for standard exhaust duct sizing\u003c\/li\u003e\n\u003cli\u003eR-2 Pro commercial-grade construction for heavy-duty exterior use\u003c\/li\u003e\n\u003cli\u003ePowder-coated black finish provides corrosion and UV resistance\u003c\/li\u003e\n\u003cli\u003eIntegrated damper prevents back-drafting and heat loss\u003c\/li\u003e\n\u003cli\u003eAnimal screen blocks pests and debris from entering ductwork\u003c\/li\u003e\n\u003cli\u003ePackaged in quantities of 3 units per package\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install termination cap for 4-inch round exhaust duct systems in residential and light commercial ventilation applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or roofing contractor.
