This vent hood mounts to an exterior wall and provides a weather-resistant termination point for rectangular duct runs. HVAC installers and contractors rely on this type of vent hood to properly terminate dryer exhaust ducts, range hood ducts, and bathroom exhaust systems that use 3-1\/4 inches x 10 inches rectangular ductwork. The aluminum construction resists corrosion and stands up to outdoor exposure, making it a durable choice for exterior wall penetrations. The 11 inches tail extends into the wall cavity, allowing for a secure connection to the interior duct run without the need for additional fittings or adapters. A properly installed vent hood prevents backdrafts, keeps pests and debris out of the duct system, and directs exhaust air away from the building exterior. The louvered or dampered design on vent hoods of this type opens under airflow and closes when the system is off, maintaining energy efficiency and indoor air quality. This product fits standard rectangular duct configurations used in kitchens, laundry rooms, and bathrooms where space-saving flat duct runs are common. The 3-1\/4 inches x 10 inches duct size is one of the most widely used profiles in residential construction, especially for under-cabinet range hoods and dryer venting in tight spaces. Builders Best is a trusted name in HVAC venting accessories, and the 111377 is built to meet the demands of professional installation crews. This vent hood is a straightforward, reliable solution for completing exterior duct terminations on rectangular duct systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e3-1\/4 inches x 10 inches rectangular duct opening fits the most common residential flat duct size\u003c\/li\u003e\n\u003cli\u003e11 inches tail provides ample depth for secure connection inside the wall cavity without extra fittings\u003c\/li\u003e\n\u003cli\u003eAluminum construction resists corrosion and withstands long-term outdoor exposure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Builders Best 111377 aluminum vent hood delivers a durable, weather-resistant exterior termination for 3-1\/4 inches x 10 inches rectangular duct systems.
