Southwark Metal ATT_10IN Duct Takeoff 10 Inch Air-tite

Product Description

The SOUTHWARK METAL ATT_10IN is a 10-inch diameter Air-Tite sheet metal duct takeoff fabricated from hot-dip galvanized steel. Duct takeoffs connect branch runs to main trunk lines in forced-air HVAC distribution systems, directing conditioned air from the trunk to individual supply runs. The hot-dip galvanized construction provides corrosion resistance suited to both residential and light commercial duct systems. This fitting meets ACCA and SMACNA standards, making it appropriate for systems designed and installed to industry specifications. HVAC sheet metal mechanics and duct installers are the primary trade using this fitting during new construction or retrofit ductwork projects.

The ATT_10IN is suited for supply or return air distribution systems where a 10-inch branch takeoff is required off a rectangular or round trunk duct. The Air-Tite design minimizes air leakage at the fitting connection point, supporting system efficiency and helping installations meet duct leakage requirements common in residential and light commercial HVAC work. This fitting is typically installed as part of a full duct system layout engineered to ACCA Manual D or similar SMACNA-compliant duct design methodology.

Key Features

• 10-inch diameter opening for direct connection to branch duct runs
• Air-Tite design reduces air leakage at the takeoff connection
• Hot-dip galvanized steel construction for corrosion resistance
• Meets ACCA and SMACNA applicable standards
• Suitable for residential and light commercial forced-air distribution systems

Compatibility

Designed as an OEM-style sheet metal fitting for use in forced-air HVAC duct systems requiring a 10-inch Air-Tite branch takeoff connection.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic. Shut down the air handler or furnace and confirm the system is de-energized before cutting into or modifying existing ductwork. Secure the fitting with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape in accordance with SMACNA duct construction standards. Follow local mechanical codes and any applicable energy code duct leakage requirements for the jurisdiction.
