Lambro Industries 344S Aluminum Dryer Vent Hood 4 Inch

Product Description

The LAMBRO INDUSTRIES 344S is a 4-inch aluminum dryer vent hood designed to terminate dryer exhaust ducts at an exterior wall. The hood features a tail sleeve with a 4-inch mouth opening that connects directly to standard round dryer duct. It is constructed from aluminum for corrosion resistance and durability in outdoor exposure. This type of fitting is installed by HVAC technicians, appliance installers, and plumbers during new construction or dryer vent system replacement. The unit ships in a package quantity of 10, making it suitable for multi-unit or contractor purchases.

The 344S is used in residential and light commercial applications wherever a dryer exhaust duct exits through an exterior wall. The 4-inch diameter matches the standard dryer duct size found in most residential installations. The tail sleeve simplifies connection to the existing duct run and helps maintain proper airflow direction away from the building envelope. Installers typically use this hood when finishing a new laundry room rough-in or replacing a damaged or inefficient vent termination.

Installation Notes

Installation is typically performed by an HVAC technician or qualified appliance installer. Disconnect the dryer from power or gas before working on the duct system. The hood should be installed on the exterior wall with the damper or louver facing downward to prevent backdraft and pest entry.
