Builders Best 11115 Aluminum Vent Hood

Product Description

The BUILDERS BEST 11115 is an aluminum vent hood designed to terminate dryer exhaust, bath fan, or similar low-pressure ventilation ductwork at an exterior wall. The aluminum construction keeps the hood lightweight and resistant to rust, making it suitable for exterior installations exposed to moisture and weather. A damper flap opens under airflow and closes when the fan shuts off, preventing backdraft and blocking pests from entering the duct system. Licensed HVAC technicians and general contractors typically install this type of fitting as the final component in a residential or light commercial exhaust run.

This vent hood fits standard round duct terminations found in residential construction and light commercial applications. It is appropriate for dryer exhaust systems, bathroom exhaust fans, kitchen range ventilation, and similar low-velocity air exhaust runs that terminate through an exterior wall. The aluminum body suits installations in coastal or high-humidity environments where steel fittings would be prone to corrosion over time.

Key Features

• Aluminum body construction for corrosion resistance in exterior applications
• Damper flap closes when airflow stops to block backdraft and pest entry
• Designed for exterior wall termination of residential exhaust ductwork
• Lightweight profile simplifies single-technician installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard residential and light commercial exterior exhaust duct terminations.

Installation Notes

Installation is typically performed by a licensed HVAC technician, plumber, or general contractor. Disconnect power to the associated fan or appliance before beginning work. Seal the hood flange to the exterior wall surface with an appropriate weatherproof caulk to prevent water infiltration. Verify local building codes and mechanical codes for required clearances from windows, doors, gas meter openings, and other penetrations before cutting the wall opening.
