Description
The Broan-NuTone 843BL Round Duct Wall Cap is useful and necessary for proper ventilation in both residential and commercial buildings in HVAC systems. Measuring for a 6-inch round duct, this wall cap comes in black, which should blend well. Its purpose is to expel air from kitchen range hoods, bathroom fans, and dryers and to provide fresh air for heating systems such as furnaces. The wall cap also has a built-in damper that prevents backdrafts, so no unwanted air is allowed to get into the home, improving energy efficiency. The wall cap has the major advantage of being high-quality and built to prevent water and pests from entering the building and maintaining indoor air quality.
