Southwark Metal 14_18X10 Trunk Duct Elbow 18x10 in 90 Deg

Product Description

The SOUTHWARK METAL 14_18X10 is a 90-degree flat Broadway sheet metal trunk duct elbow designed for rectangular HVAC ductwork systems. Fabricated from hot dip galvanized steel, this elbow maintains an 18 x 10 inch cross-section on both the inlet and outlet, making it a true same-size fitting with no reduction in airflow area. The radius throat geometry supports smoother airflow transitions through the turn compared to square-throat alternatives. This fitting is installed by licensed HVAC technicians and sheet metal mechanics during new construction ductwork runs or duct replacement projects.

The 14_18X10 is suited for residential and light commercial forced-air HVAC systems where trunk duct routing requires a 90-degree directional change. Its flat Broadway profile is commonly used in low-clearance installations such as crawlspaces, attic runs, and tight mechanical rooms where a standard radius elbow would not fit. The consistent 18 x 10 inch sizing on both ends allows direct connection to existing rectangular trunk duct sections without transitions or reducers. Applications are governed by ACCA and SMACNA standards for duct construction and installation.

Key Features

• 90-degree angle for right-angle trunk duct routing
• Hot dip galvanized steel construction for corrosion resistance in HVAC environments
• Flat Broadway style profile for use in low-clearance installations
• Radius throat design promotes smoother airflow through the bend
• Consistent 18 x 10 inch sizing on both inlet and outlet — no reduction fitting 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 elbow at an 18 x 10 inch duct size, installed per ACCA and SMACNA ductwork standards.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal mechanic. Shut down the air handling system and lock out power before cutting into or connecting to an existing duct run. Secure the elbow with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per SMACNA guidelines. Confirm that the fitting orientation matches the intended airflow direction before fastening.
