Southwark Metal 63A_9IN Square to Round Duct Takeoff 9 in

Product Description

The SOUTHWARK METAL 63A_9IN is an adjustable square-to-round duct takeoff fitting designed for connecting rectangular duct trunk lines to round branch ducts in forced-air HVAC distribution systems. Fabricated from hot-dip galvanized steel, this 9-inch diameter fitting provides a durable, corrosion-resistant transition point that meets ACCA and SMACNA standards. The adjustable design allows the technician to set the takeoff angle or position during installation, reducing the need for custom fabrication on the job site. HVAC sheet metal mechanics and duct installers use this type of fitting in both new construction and retrofit applications.

This fitting is suited for residential and light commercial forced-air duct systems where a branch run must be tapped off a rectangular supply or return trunk. The 9-inch diameter outlet accommodates standard round duct and spiral pipe of the same size. It is commonly installed in attic, crawlspace, basement, and mechanical room duct runs. The adjustable feature makes it practical for situations where branch duct routing requires flexibility in the takeoff angle relative to the trunk.

Key Features

• 9-inch diameter round outlet for standard branch duct connections
• Hot-dip galvanized steel construction for corrosion resistance in humid or unconditioned spaces
• Adjustable design reduces on-site fabrication time
• Manufactured to ACCA and SMACNA applicable standards
• Square-to-round transition profile for clean trunk-to-branch connections

Compatibility

Designed as an OEM-style sheet metal fitting compatible with standard 9-inch round duct and spiral pipe systems installed per SMACNA and ACCA duct construction guidelines.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed sheet metal mechanic familiar with SMACNA duct construction standards. Power down the air handling unit and verify the system is de-energized before cutting into an existing trunk line. Secure the fitting to the trunk with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per local mechanical code requirements. Do not exceed the duct system design static pressure for which the trunk and branch were sized.
