Southwark Metal 63AFG_6IN Ductboard Takeoff 6 Inch

Product Description

The SOUTHWARK METAL 63AFG_6IN is an adjustable square-to-round fiberglass ductboard takeoff with tab, designed for transitioning from rectangular ductboard plenums to round branch ducts. Constructed from hot dip galvanized steel, this fitting delivers corrosion resistance suited to air distribution applications in both new construction and retrofit work. The integrated tab simplifies attachment to fiberglass ductboard systems, helping technicians achieve a secure, airtight connection at the takeoff point. At 6 inches in diameter, this fitting is a standard size for residential and light commercial supply branches and is installed by licensed HVAC technicians and sheet metal mechanics.

This takeoff is intended for use in forced-air HVAC systems where fiberglass ductboard is the primary plenum or trunk material. The adjustable square-to-round design allows the fitting to seat against the ductboard surface before being secured with the tab, making it suitable for field-fabricated duct systems following ACCA and SMACNA standards. It is commonly used in residential new construction and light commercial projects where fiberglass ductboard distribution systems are specified.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic. Shut down the air handling unit and de-energize the system before cutting into existing ductboard or plenum sections. Fabricate the ductboard opening to match the fitting footprint per SMACNA ductboard installation guidelines, and secure the tab firmly to ensure an airtight seal. Seal all edges at the connection point with approved UL 181B-rated mastic or tape as required by local mechanical codes.
