Builders Best 111023A Heavy Duty Galvanized Vent Hood 4 Inches X 11 Inches with Flapper and Screen Tail Included

Product Description

The Builders Best 111023A Heavy Duty Galvanized Vent Hood is a durable, code-compliant exhaust termination fitting designed for residential and light commercial ventilation applications. Built from 26-gauge galvanized steel, this vent hood is made in the USA and engineered to handle the demands of dryer exhaust, bathroom exhaust fans, kitchen range hoods, and general HVAC ducting terminations. The unit comes complete with an 11-inch tailpipe, a built-in flapper damper, and a protective screen, making it a ready-to-install solution right out of the box. The 4-inch pipe diameter is one of the most common sizes used in residential ventilation systems, and this hood fits standard 4-inch round duct runs without adapters. The mouth opening is designed to exceed the cross-sectional area of the connected pipe, which promotes smooth, unrestricted airflow and reduces static pressure at the termination point. This is a key detail for dryer venting in particular, where back pressure can reduce appliance efficiency and increase lint buildup risk. The flapper damper closes when the exhaust fan or appliance is off, blocking cold drafts, insects, and debris from entering the duct system. The screen adds a second layer of protection against birds and rodents nesting inside the duct. Four mounting holes are pre-drilled into the face plate for secure, rattle-free attachment to exterior walls or roof soffits. The galvanized steel construction resists rust and corrosion, making it suitable for outdoor exposure in most climates. At 1.55 pounds and sized at 6 inches wide by 7.5 inches tall by 3.25 inches deep, this hood installs cleanly against standard exterior wall surfaces. HVAC installers, general contractors, and DIY homeowners will find this hood a reliable, straightforward termination solution for 4-inch round duct systems.
