Southwark Metal 63A_8IN Square to Round Duct Takeoff 8 in

Product Description

The SOUTHWARK METAL 63A_8IN is an adjustable square-to-round sheet metal duct takeoff designed for branch connections in residential and light commercial HVAC duct systems. Fabricated from hot dip galvanized steel, this fitting transitions from a rectangular main trunk to an 8-inch round branch run. The adjustable design allows the installer to set the proper angle for the branch without requiring multiple fittings on hand. It is intended for forced-air supply and return systems where a clean, low-resistance transition from the trunk line to a round branch duct is required. Licensed HVAC technicians and sheet metal contractors are the primary installers.

This takeoff is suited for residential forced-air systems and light commercial applications where galvanized steel ductwork is specified per SMACNA or ACCA standards. It connects to rectangular trunk ducts and transitions to 8-inch round branch duct. It is commonly used in new construction and retrofit duct systems where balanced airflow distribution across multiple zones or rooms is required.

Key Features

• Adjustable fitting allows branch angle to be set during installation without additional fittings
• Hot dip galvanized steel construction resists corrosion in typical HVAC duct environments
• 8-inch round outlet matches standard round branch duct and flexible duct collar sizing
• Meets ACCA and SMACNA applicable standards for sheet metal duct construction
• Square-to-round transition provides a low-turbulence airflow path from trunk to branch

Compatibility

Designed as an OEM-style sheet metal fitting for use in galvanized steel forced-air duct systems requiring a square-to-round branch takeoff with an 8-inch round outlet.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with SMACNA duct construction standards and local mechanical codes. Shut down the air handling unit and isolate the system before cutting into the trunk duct or securing the fitting. Seal all joints with listed duct sealant or mastic per applicable code requirements. Secure the fitting to the trunk with sheet metal screws and support the branch run independently to prevent stress on the takeoff connection.
