Southwark Metal 10L2020208 Universal Stackhead 20 Inches X 20 Inches to 20 Inches X 8 Inches

Product Description

The Southwark Metal 10L2020208 is a 10L Universal Stackhead designed for residential and light commercial HVAC duct systems. It transitions from a 20 inches x 20 inches plenum or trunk line down to a 20 inches x 8 inches stack outlet. This fitting is a critical component in forced-air heating and cooling systems, connecting the main supply trunk to a wall stack or floor boot. HVAC technicians and sheet metal contractors rely on stackheads like this one to efficiently route conditioned air from horizontal runs into vertical wall cavities. The 10L2020208 is fabricated from 28-gauge hot-dipped galvanized steel meeting ASTM A653 CS Type B standards. This galvanized coating protects the steel against rust and corrosion, extending service life in both new construction and replacement applications. The universal 10L design offers broad compatibility with standard residential duct layouts, reducing the need for custom fabrication on the job site. At a unit weight of 10.4 pounds and overall dimensions of 15 inches in length, 20 inches in width, and 30 inches in height, this stackhead is built for a solid, secure fit. Each unit is sold individually and is made in the USA, making it a reliable choice for contractors who need domestically sourced HVAC sheet metal components. Whether you are building a new duct system or replacing a damaged stackhead on an existing installation, the 10L2020208 delivers consistent performance and a proper air seal when correctly installed with standard duct fasteners and mastic or foil tape.
