Southwark Metal 113_7IN Duct Angle 45 Degree 7x7 Oval

Product Description

The SOUTHWARK METAL 113_7IN is a 45-degree sheet metal duct angle fitting designed for horizontal oval ductwork transitions in forced-air HVAC systems. Fabricated from hot-dip galvanized steel, this fitting meets ACCA and SMACNA fabrication standards, making it an appropriate choice for both new construction and retrofit duct installations. The 7-inch by 7-inch sizing fits flat, Broadway, longway, and oval duct profiles, giving installers flexibility across common residential and light commercial trunk-and-branch layouts. HVAC sheet metal mechanics and ductwork fabricators are the primary installers of this fitting.

This duct angle is suited for horizontal oval duct runs where a 45-degree directional change is required. The flat and oval profile compatibility makes it a practical fitting for low-clearance ceiling cavities and floor joist bays where round duct is not feasible. It is commonly used in residential forced-air heating and cooling systems as well as light commercial HVAC applications that follow SMACNA duct construction standards. The 7-inch by 7-inch dimensions address a widely used size in residential supply trunk systems.

Key Features

• 45-degree angle provides a gradual directional change to help maintain airflow efficiency in the duct run
• Hot-dip galvanized steel construction resists corrosion in typical HVAC duct environments
• Compatible with flat, Broadway, longway, and oval duct profiles for installation flexibility
• Meets ACCA and SMACNA applicable standards for duct fitting fabrication
• 7-inch by 7-inch sizing fits common residential and light commercial supply duct configurations

Compatibility

Designed for use with 7-inch by 7-inch flat, Broadway, longway, and oval horizontal sheet metal ductwork systems constructed to ACCA and SMACNA standards.

Installation Notes

Installation should be performed by a qualified HVAC sheet metal mechanic familiar with SMACNA duct construction guidelines. The duct system should be fully depressurized and the air handler powered down before modifying any section of the trunk or branch ductwork. Joints should be sealed with an approved duct sealant or mastic and mechanically fastened per the applicable code. Avoid over-driving sheet metal screws, as this can distort the fitting profile and compromise the seal at the connection point.
