Venti PBRV04 Plastic Roof Bath Vent 4 Inch Black

Product Description

The VENTI PBRV04 is a 4-inch plastic roof bath vent designed to terminate bathroom exhaust fan ductwork through a rooftop penetration. Constructed in black plastic, it provides a weather-resistant cap that prevents backdrafts, pests, and moisture intrusion while allowing exhaust air to escape. This type of fitting is a standard finish component in residential bath ventilation systems and is typically installed by roofers, HVAC technicians, or general contractors during new construction or exhaust fan upgrade projects.

This roof vent cap is suited for residential bathroom exhaust applications where a 4-inch duct terminates through the roof deck. It is commonly used in single-family homes and light residential construction to cap bathroom fan duct runs that exit through the roofline rather than through a soffit or exterior wall. The black finish is appropriate for installations on dark-colored roofing materials.

Key Features

• 4-inch duct connection sized for standard bath exhaust fan ductwork
• Black plastic construction resists corrosion and weathering
• Rooftop installation design prevents backdraft and moisture entry
• Lightweight plastic body simplifies handling and cutting during install

Compatibility

Designed as an OEM-style replacement or new-installation roof termination cap for standard 4-inch residential bathroom exhaust duct systems.

Installation Notes

Installation is typically performed by a licensed HVAC technician or qualified roofer. Shut down the connected exhaust fan at the circuit breaker before beginning work. The roof penetration should be properly flashed and sealed per local building code requirements to prevent water infiltration around the vent collar. Avoid compressing or kinking the connected duct run, as this reduces airflow and exhaust fan performance.
