Southwark Metal ATT_5IN Duct Takeoff 5 Inch Air-tite

Product Description

The SOUTHWARK METAL ATT_5IN is a 5-inch diameter Air-Tite sheet metal duct takeoff fitting fabricated from hot-dip galvanized steel. It is designed to branch airflow from a main duct trunk to a lateral run in forced-air HVAC distribution systems. The galvanized steel construction resists corrosion in both residential and light commercial environments. This fitting is manufactured to ACCA and SMACNA standards, making it a code-appropriate choice for duct systems designed and installed under Manual D or equivalent airflow design protocols. HVAC sheet metal mechanics and duct installers are the primary trade audience for this fitting.

This takeoff is suited for new construction and retrofit duct work in residential and light commercial forced-air systems. It connects to 5-inch round branch duct at the trunk line, directing conditioned air to individual room runs or equipment drops. The Air-Tite designation indicates a tighter-fitting design intended to reduce air leakage at the takeoff connection point, supporting duct system efficiency and reducing duct blaster test failures on sealed duct installations.

Key Features

• 5-inch diameter opening sized for standard round branch duct connections
• Hot-dip galvanized steel construction for corrosion resistance in conditioned and unconditioned spaces
• Air-Tite design reduces air leakage at the trunk-to-branch connection
• Manufactured to ACCA and SMACNA applicable standards
• Compatible with conventional sheet metal duct installation practices

Compatibility

Designed as an OEM-style sheet metal duct fitting for 5-inch round branch duct applications in residential and light commercial forced-air HVAC duct systems built to ACCA and SMACNA standards.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed sheet metal mechanic in accordance with SMACNA duct construction standards and local mechanical codes. Shut down and lock out the air handling unit before making any duct modifications or connections. Seal all joints with listed duct sealant or approved mastic per local code requirements to maintain system airtightness. Sheet metal screws and proper crimping tools are typically used to secure the takeoff to the trunk line and branch duct.
