Southwark Metal 16_20X10 Trunk Duct Elbow 20x10 in 90 Deg

Product Description

The SOUTHWARK METAL 16_20X10 is a 90-degree shortway sheet metal trunk duct elbow designed for rectangular HVAC ductwork systems. Constructed from hot dip galvanized steel, it provides a durable, corrosion-resistant transition point in supply or return trunk lines. The shortway vertical configuration with a radius throat minimizes turbulence and pressure drop through the turn. Both the inlet and outlet measure 20 inches by 10 inches, making this a same-size elbow with no transition offset. Sheet metal contractors and HVAC installers use this fitting when routing trunk duct around structural obstructions or making directional changes in tight vertical spaces.

This elbow is suited for residential and light commercial forced-air HVAC installations where galvanized steel trunk ductwork is specified. The shortway orientation is chosen when horizontal clearance is limited and the fitting must change direction within a reduced footprint. The radius throat design supports smoother airflow compared to square-throat fittings, reducing static pressure loss along the duct run. Fabricated to ACCA and SMACNA standards, this fitting is appropriate for systems designed and installed to meet current industry specifications.

Key Features

• 90-degree elbow angle for right-angle trunk duct routing
• Shortway vertical configuration for installations with limited horizontal clearance
• Radius throat design reduces turbulence and static pressure loss through the turn
• Hot dip galvanized steel construction for corrosion resistance in conditioned and unconditioned spaces
• Same-size inlet and outlet at 20 inches by 10 inches — no transition required
• Fabricated to ACCA and SMACNA standards

Compatibility

Designed as an OEM-style replacement or new-installation fitting for rectangular galvanized steel trunk duct systems sized at 20 inches by 10 inches.

Installation Notes

Sheet metal contractors and licensed HVAC technicians typically install trunk duct elbows as part of a forced-air distribution system. Power down the air handling equipment and verify the system is depressurized before making connections to existing ductwork. Secure the elbow to adjoining duct sections using sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per SMACNA installation guidelines. Handle cut edges with care — galvanized sheet metal edges are sharp and appropriate work gloves should be worn throughout installation.
