The Southwark Metal 901428 is a 3-piece galvanized steel reducer designed for HVAC duct systems where airflow transitions from a larger duct to a smaller one. This reducer steps down from 16 inches to 14 inches, making it a practical solution for branch runs, trunk-to-branch transitions, and air distribution layouts where duct sizing must change. HVAC technicians and sheet metal contractors rely on reducers like this one to maintain proper static pressure and airflow balance throughout a forced-air system. The 3-piece construction gives the fitting structural integrity and a clean, consistent shape that connects securely to round duct sections. The crimped end option allows for fast, tool-free insertion into the next duct section, speeding up installation on the job site. This reducer is manufactured in the USA by Southwark Metal, a trusted name in sheet metal ductwork fabrication. It is made from 28-gauge galvanized steel, which provides corrosion resistance and long service life in both residential and light commercial HVAC applications. Galvanized duct fittings are standard in forced-air heating and cooling systems because they hold up well in attic, basement, and crawl space environments where moisture exposure is possible. The unit measures 16 inches in length and 16 inches in width, with a height of 5.25 inches, fitting standard duct configurations without modification. At 1.55 pounds, it is lightweight enough to handle and position easily during installation. This product is sold individually and ships as a single unit. It meets Prop 65 requirements and carries a USA country of origin designation, which matters for contractors working on projects with domestic sourcing requirements.
The Southwark Metal 901428 3-piece galvanized steel reducer delivers a reliable 16-inch to 14-inch duct transition built to USA manufacturing standards, ideal for HVAC installers and sheet metal contractors who need a durable, code-compatible fitting that goes in fast and holds its shape.
