Southwark Metal 63AFG_7IN Ductboard Takeoff 7 in

Product Description

The SOUTHWARK METAL 63AFG_7IN is a fiberglass ductboard takeoff with tab, designed to transition airflow from a square or rectangular ductboard plenum into a round branch duct. Constructed from hot dip galvanized steel, it offers corrosion resistance in typical forced-air HVAC applications. The adjustable, square-to-round design allows the collar to seat firmly against ductboard surfaces, while the integrated tab provides a positive mechanical connection point. This fitting is installed by licensed HVAC technicians during new construction or retrofit duct fabrication work where fiberglass ductboard systems are specified.

This takeoff is suited for residential and light commercial forced-air systems using fiberglass ductboard construction. It connects trunk or plenum ductboard to 7-inch round branch runs, making it a standard fitting in supply-side duct layouts. The adjustable feature accommodates field fitting during installation, reducing the need for custom cutting or additional transitions. HVAC sheet metal mechanics and duct installers working on ductboard systems will find this fitting applicable to a range of supply distribution configurations.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in conditioned-air environments
• Adjustable square-to-round design for field-fit flexibility during ductboard installation
• Integrated tab provides a secure mechanical attachment point to ductboard surface
• 7-inch diameter outlet connects directly to standard round branch duct
• Meets ACCA and SMACNA applicable standards for duct fittings

Compatibility

Designed as an OEM-style fitting for fiberglass ductboard HVAC systems requiring a square-to-round branch takeoff at a 7-inch diameter round duct connection.

Installation Notes

Installation should be performed by a qualified HVAC technician familiar with fiberglass ductboard systems and SMACNA ductwork standards. Power down the air handling unit and verify the system is de-energized before beginning duct modifications. The tab should be secured to the ductboard surface using approved ductboard adhesive and mechanical fasteners per SMACNA and ACCA guidelines. Seal all joints with UL 181B-rated tape or mastic appropriate for fiberglass ductboard applications.
