Southwark Metal AT63A_6IN Duct Takeoff 6 Inch Adjustable

Product Description

The SOUTHWARK METAL AT63A_6IN is a 6-inch adjustable, Air-Tite sheet metal duct takeoff fabricated from hot dip galvanized steel. Duct takeoffs connect branch runs to main trunk ducts, directing conditioned air from the primary duct system into individual supply runs. This fitting is built to ACCA and SMACNA standards, making it appropriate for forced-air residential and light commercial HVAC installations. The galvanized steel construction resists corrosion in both exposed and concealed duct applications. The adjustable design allows the installer to set the takeoff angle or position during rough-in, reducing the need for additional transition fittings in tight spaces. HVAC installers and sheet metal mechanics are the primary trades working with this component.

This takeoff is suited for use in low-pressure supply duct systems where a 6-inch round branch connection is required off a rectangular or round main trunk. Typical installations include residential forced-air systems using flex or rigid round duct for room supply runs. The Air-Tite designation indicates a design intended to minimize air leakage at the fitting joint, supporting duct system efficiency. It is commonly used in new construction and replacement duct work where SMACNA-compliant fittings are specified.

Key Features

• 6-inch diameter branch opening for standard round duct connections
• Adjustable design allows positioning flexibility during installation
• Air-Tite construction reduces air leakage at the fitting joint
• Hot dip galvanized steel provides corrosion resistance for long service life
• Meets ACCA and SMACNA applicable standards for duct fabrication and performance

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 6-inch round branch duct connections in residential and light commercial forced-air duct systems built to SMACNA standards.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal mechanic. The HVAC system should be powered down and the air handler shut off before cutting into an existing trunk duct. Sheet metal snips, a hole saw or plasma cutter, and sheet metal screws or drive cleats are common tools for this fitting type. Seal all joints with UL 181-rated mastic or foil tape in accordance with local mechanical codes and SMACNA installation guidelines.
