Southwark Metal 14_20X8 Trunk Duct Elbow 20x8 Inch 90 Degree

Product Description

The SOUTHWARK METAL 14_20X8 is a 90-degree sheet metal trunk duct elbow designed for rectangular HVAC duct systems. It features a flat, Broadway-style configuration with a radius throat, which promotes smoother airflow through the turn compared to square-throat fittings. Constructed from hot dip galvanized steel, this elbow measures 20 inches by 8 inches at both the inlet and outlet. It is used in forced-air heating and cooling distribution systems and is typically installed by licensed sheet metal workers or HVAC technicians during new construction or system retrofit work.

This trunk duct elbow is suited for residential and light commercial forced-air HVAC applications where a 90-degree directional change in rectangular ductwork is required. The Broadway flat-style elbow fits into tight plenum and overhead spaces where a standard-radius elbow would not clear structural members. The 20 x 8 inch sizing matches common trunk duct runs off air handlers and furnace plenums. Conformance to ACCA and SMACNA standards makes this fitting appropriate for code-compliant duct system installations.

Key Features

• 90-degree angle for right-angle trunk duct transitions
• Flat, Broadway configuration suits low-clearance installations
• Radius throat design reduces turbulence and static pressure loss at the elbow
• Hot dip galvanized steel construction resists corrosion in conditioned and unconditioned spaces
• Inlet and outlet both sized at 20 inches by 8 inches for straight-through sizing compatibility
• Meets ACCA and SMACNA applicable standards for duct fabrication and installation

Compatibility

Designed as an OEM-style sheet metal fitting for rectangular trunk duct systems in residential and light commercial forced-air HVAC installations.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed sheet metal worker in accordance with SMACNA duct construction standards and local mechanical codes. Shut down and de-energize the air handling system before connecting or modifying ductwork. Secure all duct connections with sheet metal screws and seal with code-approved mastic or UL-listed foil tape to minimize air leakage. Handle cut edges with care to avoid injury from sharp galvanized steel.
