Southwark Metal 62FG_7IN Ductboard Top Takeoff 7 in

Product Description

The SOUTHWARK METAL 62FG_7IN is a non-adjustable, square-to-round fiberglass ductboard top takeoff designed for use in residential and light commercial HVAC duct systems. Built from hot dip galvanized steel, this fitting transitions from a flat ductboard plenum surface to a 7-inch round duct collar. The 1-inch tab provides a secure attachment point to the ductboard surface, and the raised back design promotes proper airflow geometry at the takeoff point. HVAC installers and sheet metal contractors use this type of fitting when building out trunk-and-branch duct systems using fiberglass ductboard.

This fitting is intended for fiberglass ductboard plenum and trunk applications where a top-mounted round branch takeoff is required. The square-to-round profile transitions the flat ductboard surface to a 7-inch round collar, which connects to branch runs of matching diameter. Typical installation scenarios include new construction and replacement ductwork in low-pressure, residential forced-air systems. Fabrication and installation should conform to ACCA and SMACNA standards for ductboard construction and joint sealing.

Key Features

• 7-inch diameter round collar for direct connection to matching branch duct
• Hot dip galvanized steel construction for corrosion resistance
• 1-inch tab for positive attachment to fiberglass ductboard surface
• Raised back design supports proper airflow transition geometry
• Non-adjustable, fixed square-to-round profile for consistent fitment
• Meets ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style replacement and new-construction fitting for fiberglass ductboard plenum and trunk systems requiring a 7-inch diameter top takeoff connection.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Power down the air handler and close the fuel supply or disconnect the system before working inside the plenum or duct system. Secure the tab to the ductboard surface using approved ductboard adhesive and mechanical fasteners per SMACNA ductboard construction guidelines. Seal all joints with UL 181B-rated tape or mastic appropriate for fiberglass ductboard systems.
