The Southwark Metal 27R6149 is a straight register boot designed for residential and commercial HVAC duct systems. It connects rectangular ductwork to a floor, wall, or ceiling register opening. HVAC installers and sheet metal contractors use this boot to transition from a standard duct run to a register or grille at the point of air delivery. The boot size is 6 inches x 14 inches with a 9 inch collar, giving it a clear, defined airflow path from the collar into the boot cavity. This straight configuration keeps installation simple and direct, with no offset or angle to work around. The boot is manufactured from 30 gauge galvanized steel, which provides corrosion resistance and structural rigidity for long-term performance inside walls, floors, and subfloor cavities. Galvanized steel is the industry standard material for HVAC sheet metal fittings because it handles temperature cycling, humidity, and air pressure without degrading. This boot is not flanged and not insulated, making it suitable for standard unconditioned plenum or interior installations where insulation is applied separately or not required. The unflanged design allows for a clean fit into framed openings without added bulk. Southwark Metal is a well-known domestic manufacturer of sheet metal HVAC products, and the 27R6149 is made in the USA. It is sold individually as a single unit. This boot is part of the 27R product family from Southwark, which covers a range of standard register boot sizes and configurations used by HVAC professionals across residential new construction, replacement projects, and light commercial applications. The 30 gauge thickness is appropriate for register boot applications where the fitting is stationary and not subject to heavy mechanical stress.
The Southwark Metal 27R6149 delivers a reliable, code-compatible straight register boot in galvanized steel for standard residential and light commercial HVAC duct installations. Its domestic manufacture and straightforward design make it a practical choice for HVAC contractors and sheet metal installers.
