The GV0071 8 in. x 20 in. 90-degree flat elbow is an essential duct fitting designed to alter the path of rectangular ductwork by a sharp right angle horizontally. Built from reliable 28-gauge galvanized steel, this component provides the strength and rigid structure required for horizontal trunk lines or large branch distributions. It facilitates smooth directional airflow changes while maintaining a low profile in tight structural spaces.
This flat elbow is tailored for HVAC installers and commercial contractors managing layouts inside restricted spaces, such as shallow ceilings or floor joists. The horizontal configuration enables the duct line to turn without dropping or raising the profile, keeping the system compact and clear of other utilities. Its galvanized coating shields the sheet metal from atmospheric moisture and corrosion, promoting reliable air delivery over extended operation.
When planning your ventilation configuration, matching the 8-inch by 20-inch connection size with your main supply plenum or duct run is vital to prevent static pressure imbalances. This unit links securely to straight ducts using standard drive slips or S-cleats and can be fully sealed with mastic or foil tape. Verify your layout paths and dimensions to integrate this flat elbow cleanly into your next mechanical project.
