Southwark Metal 63A_7IN Square to Round Duct Takeoff 7 in

Product Description

The SOUTHWARK METAL 63A_7IN is an adjustable square to round duct takeoff fabricated from hot dip galvanized steel. It transitions airflow from a rectangular main trunk duct to a round branch duct and is a standard fitting in forced-air HVAC distribution systems. The 7-inch diameter outlet matches common round duct and spiral pipe sizes used in residential and light commercial installations. The adjustable design allows the fitting to be positioned at varying angles along the trunk, giving installers flexibility when laying out branch runs. HVAC sheet metal mechanics and duct installers are the primary trades working with this fitting.

This takeoff is used in new construction and retrofit forced-air systems where a square or rectangular trunk duct supplies a round branch run. Typical applications include residential gas furnace and air handler duct systems as well as light commercial rooftop unit distribution. The fitting is suited for supply-air trunk-to-branch connections where a clean, secure transition is required. Its galvanized construction makes it appropriate for both conditioned space and attic installations where moisture resistance is a consideration.

Key Features

• Adjustable fitting allows repositioning along the trunk duct without a fixed-angle commitment
• Hot dip galvanized steel construction provides corrosion resistance for long service life
• 7-inch diameter outlet connects directly to standard round duct and fittings
• Meets ACCA and SMACNA fabrication and application standards
• Square to round geometry handles trunk-to-branch transitions in a single fitting

Compatibility

Designed as an OEM-style sheet metal fitting for use with standard rectangular trunk ducts and 7-inch round branch duct systems in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation is performed by licensed HVAC mechanics or qualified sheet metal workers in accordance with SMACNA duct construction standards and local mechanical codes. Shut down and lock out the air handler or furnace before cutting into an existing trunk duct. Secure the takeoff collar to the trunk with sheet metal screws and seal all joints with UL 181-rated mastic or approved foil tape to meet duct leakage requirements. Do not rely on friction fit alone for branch connections.
