The Southwark Metal 24R6149 is a 90-degree register boot designed for residential and light commercial HVAC duct systems. It connects rectangular ductwork to floor, wall, or ceiling registers, directing conditioned air from the supply duct into the living space. HVAC installers, sheet metal contractors, and mechanical tradespeople rely on this type of boot to complete supply air distribution runs efficiently and accurately. The 24R6149 features a 6-inch by 14-inch boot opening and a 9-inch round collar, making it compatible with standard 9-inch round flex duct or rigid duct connections. The 90-degree elbow configuration allows the duct run to turn and terminate at the register face in a compact, clean installation. The body is fabricated from 30 gauge hot dipped galvanized steel meeting ASTM A653 CS Type B standards with a G40 coating rating, providing corrosion resistance suitable for in-floor, in-wall, and subfloor applications. The collar is constructed from 28 gauge steel, adding rigidity at the duct connection point. A 1 half inch rise accommodates register placement and maintains proper airflow alignment. The register opening has a 1 quarter inch hemmed edge for a clean, safe finish, while the collar features a 1 eighth inch hemmed edge. Rivet tabs measuring 1 half inch accept 1 eighth inch rivets for secure mechanical attachment to ductwork. The register opening depth is 3 inches, with a plus or minus 1 quarter inch tolerance. This boot ships as a single unit and is manufactured in the USA. It is not insulated and not flanged, keeping installation straightforward for standard duct rough-in work.
The Southwark Metal 24R6149 delivers a durable, code-compliant register boot connection for 9-inch round duct systems, built to ASTM standards from USA-manufactured hot dipped galvanized steel. Its 90-degree design and precise dimensions make it a reliable choice for HVAC supply air terminations in residential and commercial construction.
