Southwark Metal HT15_8X7 Adjustable Round Duct Takeoff

Product Description

The SOUTHWARK METAL HT15_8X7 is an adjustable round sheet metal duct takeoff designed for branch connections in residential and light commercial HVAC duct systems. Fabricated from hot dipped galvanized steel, this fitting provides a durable, corrosion-resistant connection point where a branch duct splits from the main trunk. The half tab design simplifies installation by giving the installer a secure fold-over locking point without additional fasteners. Size A measures 8 inches in diameter and Size B measures 7 inches in diameter, making it suitable for standard trunk-to-branch transitions in forced-air distribution systems.

This takeoff is used in sheet metal ductwork installations where an adjustable, round branch fitting is needed off a main duct trunk. HVAC sheet metal mechanics and duct installers specify this fitting for new construction and retrofit duct systems. It is well suited for residential forced-air heating and cooling applications as well as light commercial ventilation layouts that follow SMACNA and ACCA fabrication standards.

Key Features

• Hot dipped galvanized steel construction for corrosion resistance in HVAC duct environments
• Adjustable design allows positioning of the branch outlet to match field layout requirements
• Half tab inclusion provides a positive lock during installation without extra hardware
• Round profile compatible with standard round branch duct and flexible duct connections
• Meets ACCA and SMACNA applicable standards for sheet metal duct fittings

Compatibility

Designed as an OEM-style replacement and new-construction fitting for standard round branch duct takeoff applications in residential and light commercial forced-air duct systems built to SMACNA and ACCA guidelines.

Installation Notes

Installation is typically performed by licensed sheet metal mechanics or HVAC technicians following SMACNA duct construction standards. Power down the air handling system before cutting into or modifying any existing ductwork. Secure the fitting to the trunk duct using the half tab and appropriate sheet metal screws, then seal all joints with UL 181-listed mastic or foil tape per local mechanical code requirements. Do not over-bend or distort the adjustable collar, as this can compromise the airtight seal at the branch connection.
