The SOUTHWARK METAL EP15_6X5 is a round-to-round sheet metal duct takeoff designed for branch connections in low-pressure residential and light commercial HVAC duct systems. Fabricated from hot dip galvanized steel, this fitting transitions airflow from a 6-inch diameter main duct to a 5-inch diameter branch run. The full tab, adjustable design allows the installer to position the takeoff at various angles along the main duct, reducing the need for additional fittings and simplifying layout. HVAC sheet metal mechanics and duct installers specify this type of fitting for supply trunk-to-branch connections in forced-air systems.
This takeoff is suited for round duct systems in residential forced-air heating and cooling installations as well as light commercial applications where SMACNA and ACCA ductwork standards apply. The adjustable full tab configuration makes it a practical choice for new construction and retrofit jobs where branch takeoff positioning must be determined in the field. It connects a 6-inch diameter trunk or collar to a 5-inch diameter branch duct run.
Designed as an OEM-style replacement and new-installation fitting for round sheet metal duct systems requiring a 6-inch to 5-inch branch takeoff connection in residential and light commercial forced-air HVAC applications.
Installation is typically performed by licensed sheet metal mechanics or HVAC installers. Shut down the air handling unit and verify the system is depressurized before cutting into any existing duct trunk. Secure the full tabs firmly against the duct surface and seal all connections with UL 181-listed mastic or foil tape in accordance with local mechanical codes and SMACNA installation guidelines. Avoid over-bending the tabs, as repeated flexing can compromise the galvanized coating at the connection point.
