Southwark Metal EP15_8X7 Round to Round Duct Takeoff 8x7

Product Description

The SOUTHWARK METAL EP15_8X7 is a round-to-round sheet metal duct takeoff designed for branch connections in residential and light commercial HVAC duct systems. Fabricated from hot dip galvanized steel, it provides durable corrosion resistance in both supply and return air applications. The full tab, adjustable design allows the fitting to be positioned and locked along the main trunk or round duct run, making field installation straightforward. Sized at 8 inches on the inlet and 7 inches on the outlet, it suits common trunk-to-branch transitions in forced-air systems. HVAC sheet metal installers and duct fabricators are the primary trade installing this fitting.

This takeoff is used in forced-air heating and cooling duct systems where a branch line must be tapped off a round main duct. The adjustable full tab style allows the installer to rotate the fitting to the desired angle before securing it in place, accommodating varied layout configurations in tight mechanical spaces. It is built to meet ACCA and SMACNA standards, making it appropriate for duct systems that must conform to those industry specifications. Typical install scenarios include new construction trunk-and-branch layouts and retrofit branch additions in residential and light commercial buildings.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in HVAC duct environments
• Full tab design provides a secure, positive lock once positioned on the main duct
• Adjustable fitting allows rotation to the desired branch angle before final installation
• Round-to-round configuration connects an 8-inch main duct to a 7-inch branch
• Meets ACCA and SMACNA applicable standards for duct fabrication and installation

Compatibility

Designed as an OEM-style replacement and new-installation fitting for round duct trunk-and-branch systems conforming to ACCA and SMACNA duct construction standards.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal duct installers. The air handling system should be powered down and the air handler or furnace shut off before cutting into any existing duct run. Secure the full tab to the main duct using sheet metal screws and seal all joints with UL 181-rated duct mastic or foil tape per applicable mechanical codes. Follow SMACNA installation guidelines and local mechanical code requirements for support spacing and joint sealing.
