Southwark Metal 14_20X10 Trunk Duct Elbow 20x10 in 90 Deg

Product Description

The SOUTHWARK METAL 14_20X10 is a flat, Broadway-style sheet metal trunk duct elbow designed for rectangular HVAC ductwork systems. Constructed from hot dip galvanized steel, this fitting makes a 90-degree directional change while maintaining a consistent 20 inch x 10 inch cross-section from inlet to outlet. The radius throat profile reduces turbulence and pressure drop at the turn, supporting balanced airflow distribution in forced-air systems. This fitting is fabricated to ACCA and SMACNA standards, making it appropriate for commercial and residential sheet metal duct installations. Sheet metal mechanics and HVAC installers use this elbow as a primary trunk line component where a right-angle transition is required.

This elbow is suited for low-pressure rectangular trunk duct systems in both residential and light commercial forced-air heating and cooling applications. The Broadway flat style is a common configuration in basement, crawlspace, and attic duct runs where vertical clearance is limited and a wide, shallow trunk profile is preferred. The radius throat geometry is specified in SMACNA duct construction standards to improve airflow efficiency compared to square-throat fittings. Installers working to Manual D load calculations and SMACNA Sheet Metal and Air Conditioning Construction guidelines will find this fitting consistent with those specifications.

Key Features

• 90-degree trunk duct elbow for right-angle direction changes in rectangular duct systems
• Hot dip galvanized steel construction provides corrosion resistance for long service life
• Flat Broadway profile suits installations with limited vertical clearance
• Radius throat design reduces turbulence and static pressure loss at the turn
• Consistent 20 inch x 10 inch sizing at both inlet and outlet — no size transition required
• Fabricated in compliance with ACCA and SMACNA applicable standards

Compatibility

Designed for use with 20 inch x 10 inch rectangular sheet metal trunk duct systems constructed to ACCA and SMACNA standards. Compatible with flat, Broadway-profile rectangular duct assemblies of matching cross-section.

Installation Notes

Installation should be performed by a licensed sheet metal mechanic or qualified HVAC technician. Shut down the air handling unit and confirm the system is de-energized before connecting or modifying any duct section. Secure the elbow to adjoining duct sections using sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per applicable code requirements. Reference SMACNA duct construction standards and local mechanical codes for hanger spacing, support requirements, and joint sealing specifications.
