Southwark Metal 63AFG_8IN Ductboard Takeoff 8 Inch

Product Description

The SOUTHWARK METAL 63AFG_8IN is an adjustable square-to-round fiberglass ductboard takeoff with tab, designed for transitioning from rectangular ductboard plenums to round branch ducts. Built from hot dip galvanized steel, this fitting provides a durable, corrosion-resistant connection point in forced-air HVAC distribution systems. The integrated tab secures the fitting to fiberglass ductboard panels without the need for additional fasteners at the takeoff point. With an 8-inch diameter outlet, it suits a wide range of residential and light commercial supply branch runs. HVAC sheet metal installers and duct fabricators are the primary tradespeople who work with this component.

This takeoff is used in forced-air heating and cooling systems where fiberglass ductboard is the primary trunk and plenum material. The adjustable square-to-round design allows the installer to size the fitting to the ductboard opening during fabrication, accommodating varying trunk widths. It is well suited for new construction and retrofit applications where a clean, low-leakage branch connection from a flat ductboard surface to an 8-inch round branch duct is required. Compliance with ACCA and SMACNA standards makes this fitting appropriate for installations governed by those specifications.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in conditioned air environments
• Adjustable square-to-round profile accommodates varying ductboard trunk dimensions
• Integrated tab for positive attachment directly to fiberglass ductboard panels
• 8-inch diameter outlet for standard round branch duct connections
• Meets ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style fitting for fiberglass ductboard HVAC distribution systems requiring a square-to-round branch takeoff at an 8-inch diameter outlet.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal installer. The air handling unit or furnace should be shut down and the system de-energized before cutting into any ductboard surface or installing branch takeoffs. Use appropriate ductboard knives and cutting tools to size the plenum opening to match the fitting footprint. Seal all joints with UL 181B-rated tape or mastic per SMACNA and local mechanical code requirements.
