Southwark Metal 14_16X8 Trunk Duct Elbow 16x8 in 90 Deg

Product Description

The SOUTHWARK METAL 14_16X8 is a 90-degree flat Broadway radius throat sheet metal trunk duct elbow used to redirect rectangular ductwork in forced-air HVAC systems. Constructed from hot dip galvanized steel, this elbow transitions a 16-inch x 8-inch duct inlet to a 16-inch x 8-inch duct outlet, maintaining the same cross-section through the turn. The radius throat design reduces turbulence and pressure drop at the elbow, which is a practical advantage in trunk-and-branch duct systems. Licensed HVAC technicians and sheet metal installers handle this type of fitting during new construction and retrofit jobs.

This elbow is intended for rectangular trunk duct systems in residential and light commercial forced-air heating and cooling applications. The flat, Broadway profile suits installations where vertical clearance is limited, such as in tight joist bays or low-profile plenum spaces. The 90-degree angle makes it a standard choice for corners and direction changes in supply or return trunk runs. It meets ACCA and SMACNA applicable standards, which are the governing references for duct fabrication and system performance in the HVAC trade.

Key Features

• 90-degree turn angle for standard right-angle trunk duct direction changes
• Flat Broadway profile suited for low-clearance installations
• Radius throat construction reduces airflow turbulence and static pressure loss
• Hot dip galvanized steel construction resists corrosion in unconditioned spaces
• Consistent 16-inch x 8-inch inlet and outlet dimensions maintain duct sizing through the elbow
• Meets ACCA and SMACNA standards for duct system fabrication

Compatibility

Designed as an OEM-style sheet metal fitting for rectangular trunk duct systems requiring a 16-inch x 8-inch 90-degree flat elbow in forced-air HVAC installations built to ACCA and SMACNA standards.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal workers. Power down the air handling unit and close any associated dampers before working on the duct system. Secure the elbow to adjoining duct sections using sheet metal screws and seal all joints with UL-listed duct mastic or metal foil tape per SMACNA installation guidelines. Avoid using standard cloth duct tape, which does not meet code requirements for duct sealing.
