Southwark Metal ATSD_14IN Duct Takeoff 14 Inch

Product Description

The SOUTHWARK METAL ATSD_14IN is an Air-Tite sheet metal duct takeoff fitting designed for forced-air HVAC distribution systems. Constructed from hot dip galvanized steel, it provides a durable, corrosion-resistant connection point between a main trunk duct and a branch run. The 14-inch diameter opening accommodates high-volume branch applications where airflow capacity and a tight seal are both required. An integrated scoop improves air capture from the trunk, while the built-in damper allows field balancing of airflow to individual zones. Licensed HVAC technicians and sheet metal contractors are the primary installers of this fitting.

This takeoff is suited for residential and light commercial forced-air systems where branch duct runs connect to rectangular or round trunk ducts. The Air-Tite construction helps minimize duct leakage, supporting system efficiency goals required by many local energy codes. It is appropriate for new construction installations and retrofit trunk-and-branch duct systems where a 14-inch branch connection is specified by the design load calculation.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in attic, crawlspace, and mechanical room environments
• Integrated scoop improves airflow capture from the main trunk duct
• Built-in damper allows field balancing of branch airflow without separate hardware
• Air-Tite design reduces duct leakage at the takeoff connection point
• Meets ACCA and SMACNA applicable standards for sheet metal ductwork

Compatibility

Designed as an OEM-style sheet metal duct takeoff for forced-air HVAC trunk-and-branch distribution systems requiring a 14-inch diameter branch connection point.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with SMACNA duct construction standards and applicable local mechanical codes. Shut down and lock out the air handling unit before cutting into the trunk duct or securing the takeoff. Seal all joints with code-compliant duct sealant or mastic after mechanical fastening to maintain Air-Tite performance. Set the integral damper position during system commissioning as part of the overall airflow balancing procedure.
