Southwark Metal 14_14X8 Trunk Duct Elbow 14x8 90 Deg

Product Description

The SOUTHWARK METAL 14_14X8 is a flat, Broadway-style sheet metal trunk duct elbow designed for rectangular HVAC ductwork systems. Fabricated from hot dip galvanized steel, this elbow makes a 90-degree direction change while maintaining a consistent 14 x 8 inch cross-section from inlet to outlet. The radius throat profile supports smoother airflow transition through the bend compared to sharp-throat fittings. This fitting is sized and built to meet ACCA and SMACNA standards, making it appropriate for engineered duct systems where fitting geometry and material quality are specified by design. Licensed HVAC sheet metal mechanics are the typical installers for this type of trunk fitting.

This elbow is used in residential and light commercial forced-air HVAC systems where rectangular trunk ductwork requires a 90-degree turn. The Broadway flat elbow configuration is a standard fitting type in low-profile or space-constrained installations where duct depth is limited in one dimension. Both the inlet and outlet are 14 inches x 8 inches, making this a same-size transition fitting rather than a reducing elbow. It is suited for supply or return trunk applications in new construction and retrofit duct systems built to SMACNA or ACCA Manual D specifications.

Key Features

• 90-degree angle for standard trunk duct direction changes
• Hot dip galvanized steel construction for corrosion resistance in HVAC environments
• Broadway flat elbow profile suited for low-clearance duct installations
• Radius throat design promotes smoother airflow and reduced pressure drop through the bend
• Same-size inlet and outlet: 14 inches x 8 inches on both ends
• Meets ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style sheet metal fitting for rectangular trunk ductwork systems requiring a 90-degree flat elbow at 14 inches x 8 inches duct size, conforming to ACCA and SMACNA fitting specifications.

Installation Notes

Installation should be performed by a licensed HVAC sheet metal mechanic or journeyman following applicable SMACNA duct construction standards and local mechanical codes. Power down the air handling system before connecting or modifying any duct sections. Secure the elbow to adjoining duct sections using drive cleats, S-cleats, or screws as specified by the duct construction class, and seal all joints with UL 181-listed mastic or foil tape to maintain system air tightness. Do not modify the fitting geometry by cutting or deforming the radius throat, as this will affect pressure drop and airflow performance.
