Southwark Metal 63A_5IN Square to Round Duct Takeoff 5 in

Product Description

The SOUTHWARK METAL 63A_5IN is a square to round duct takeoff fitting designed for sheet metal ductwork in forced-air HVAC systems. Manufactured from hot dip galvanized steel, this fitting transitions airflow from a rectangular main trunk or plenum to a round branch duct with a 5-inch diameter outlet. The adjustable design allows the fitting to seat against flat or curved trunk surfaces, giving installers flexibility during layout. This type of fitting is standard in residential and light commercial duct fabrication work and is installed by HVAC technicians and sheet metal mechanics during new construction and retrofit projects.

The 63A_5IN is suited for use in supply and return air duct systems where a round branch run must be tapped off a rectangular main trunk. The 5-inch diameter outlet accommodates standard 5-inch round duct or flexible duct connections. Its adjustable construction makes it applicable across a range of trunk configurations commonly encountered in residential new construction, HVAC retrofit work, and light commercial installations. Fabrication and installation follow SMACNA and ACCA duct construction standards.

Key Features

• 5-inch diameter outlet for connection to standard round or flexible branch duct
• Hot dip galvanized steel construction for corrosion resistance in conditioned and unconditioned spaces
• Adjustable design accommodates varying trunk duct surface profiles
• Compliant with ACCA and SMACNA applicable standards for duct construction
• Square to round transition eliminates the need for a separate reducing fitting at the branch tap

Compatibility

Designed as an OEM-style sheet metal fitting compatible with standard rectangular trunk duct systems requiring a 5-inch round branch takeoff, fabricated and installed in accordance with SMACNA and ACCA duct construction guidelines.

Installation Notes

Installation is performed by licensed HVAC technicians or journeyman sheet metal mechanics. The system should be fully de-energized and the air handler or furnace shut down before cutting into an existing trunk duct. Sheet metal screws and UL-listed foil tape or mastic sealant are used to secure and seal the fitting per SMACNA standards. Follow local mechanical codes and ACCA Manual D duct design requirements when sizing and positioning branch takeoffs.
