Southwark Metal 14_30X8 Trunk Duct Elbow 30x8 in 90 Degree

Product Description

The SOUTHWARK METAL 14_30X8 is a flat, Broadway-style rectangular trunk duct elbow designed for 90-degree turns in sheet metal duct systems. Fabricated from hot dip galvanized steel, this elbow provides corrosion-resistant performance in residential and light commercial HVAC ductwork. The flat Broadway configuration suits installations where space constraints require a low-profile elbow geometry. With both inlet and outlet dimensions of 30 inches by 8 inches, it integrates directly into matching trunk duct runs without reducers or adapters. HVAC sheet metal fabricators and installers use this fitting where the supply or return trunk must change direction while maintaining full cross-sectional area.

This elbow is used in forced-air HVAC systems as part of a main trunk duct assembly. It suits rectangular duct layouts built to ACCA and SMACNA standards, which govern duct sizing, construction, and airflow performance. Typical installations include attic, basement, and crawlspace duct systems where the main trunk must navigate around structural framing or mechanical obstructions. The 90-degree angle and flat Broadway profile make it a standard choice in trunk-and-branch duct designs.

Key Features

• 90-degree elbow angle for right-angle trunk duct direction changes
• Hot dip galvanized steel construction for corrosion resistance in humid or unconditioned spaces
• Flat Broadway rectangular profile suited to space-constrained installations
• Matching 30 x 8 inch inlet and outlet dimensions maintain full duct cross-section
• Built to ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style sheet metal fitting for rectangular trunk duct systems with 30 x 8 inch duct dimensions built to ACCA and SMACNA construction standards.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal workers. Power down the air handler or furnace before working on the duct system. Secure the elbow to adjoining duct sections using sheet metal screws and seal all joints with UL 181-rated duct sealant or mastic per SMACNA guidelines. Avoid overtightening fasteners at the elbow flanges, as this can deform the galvanized steel and compromise the seal.
