Southwark Metal AT63A_7IN Adjustable Duct Takeoff 7 Inch

Product Description

The SOUTHWARK METAL AT63A_7IN is an adjustable, Air-Tite sheet metal duct takeoff designed for branch connections in forced-air HVAC duct systems. Constructed from hot dip galvanized steel, this 7-inch diameter fitting provides a secure, low-leakage tap off a main trunk duct or plenum. The adjustable design allows the collar angle to be set during installation, improving fit across a range of duct configurations. Licensed HVAC technicians and sheet metal contractors use this type of fitting in both new construction and retrofit residential and light commercial ductwork installations.

This takeoff is suited for residential and light commercial forced-air systems where a 7-inch branch run is required off a rectangular or round trunk. It is appropriate for supply-side duct layouts designed to ACCA Manual D standards. The adjustable feature makes it practical for angled or offset branch runs where a fixed takeoff would not align cleanly. Installers working on new construction or duct modification projects will find this fitting compatible with standard sheet metal fabrication practices per SMACNA guidelines.

Key Features

• 7-inch diameter branch opening fits standard 7-inch round duct and flex duct collars
• Hot dip galvanized steel construction resists corrosion in unconditioned spaces such as attics and crawlspaces
• Air-Tite design reduces duct leakage at the branch connection point
• Adjustable collar allows angle setting at installation to accommodate varied duct routing
• Meets ACCA and SMACNA applicable standards for sheet metal duct fittings

Compatibility

Designed as an OEM-style sheet metal duct fitting for use in residential and light commercial forced-air HVAC duct systems requiring a 7-inch adjustable branch takeoff connection.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with SMACNA duct construction standards and local mechanical codes. Shut down the air handler or furnace and de-energize the system before cutting into an existing trunk duct. Secure the takeoff with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape to maintain system air tightness. Do not flex or distort the collar during installation, as this can compromise the Air-Tite seal.
