Southwark Metal 14_22X8 Trunk Duct Elbow 22x8 in 90 Deg

Product Description

The SOUTHWARK METAL 14_22X8 is a 90-degree sheet metal trunk duct elbow designed for rectangular ductwork systems in forced-air HVAC installations. Fabricated from hot-dip galvanized steel, this fitting features a Broadway flat profile with a radius throat, maintaining a consistent 22 inches x 8 inches cross-section at both the inlet and outlet. The radius throat geometry reduces turbulence and pressure drop through the turn compared to square-throat alternatives. HVAC sheet metal mechanics and duct fabricators install this fitting where a trunk duct must change direction by 90 degrees while keeping the rectangular profile intact.

This elbow is suited for residential and light commercial forced-air systems where rectangular trunk duct runs require a 90-degree directional change. The Broadway flat elbow configuration is commonly used in low-clearance ceiling and attic installations where vertical stack height is limited. Both inlet and outlet dimensions are 22 inches x 8 inches, making this a straight-size fitting with no transition. Installers specify this type of fitting in supply or return trunk duct assemblies built to ACCA and SMACNA standards.

Key Features

• 90-degree angle for full directional change in rectangular trunk duct runs
• Hot-dip galvanized steel construction for corrosion resistance in HVAC duct systems
• Broadway flat profile suits low-clearance installation environments
• Radius throat design reduces airflow turbulence and static pressure loss through the elbow
• Consistent 22 inches x 8 inches size at both ends — no transition required
• Meets ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style sheet metal fitting for rectangular trunk duct systems requiring a 90-degree Broadway flat elbow at 22 inches x 8 inches.

Installation Notes

Installation of sheet metal duct fittings is typically performed by licensed HVAC mechanics or sheet metal workers. Power down the air handler or furnace and relieve any system pressure before making duct modifications. Fittings should be secured with sheet metal screws and sealed with approved duct sealant or mastic per SMACNA installation guidelines to prevent air leakage. Follow all applicable local mechanical codes and ACCA Manual D duct design requirements when integrating this elbow into a duct system.
