Southwark Metal 16_16X8 Trunk Duct Elbow 16x8 Shortway 90

Product Description

The SOUTHWARK METAL 16_16X8 is a 90-degree sheet metal trunk duct elbow designed for rectangular HVAC ductwork systems. Fabricated from hot dip galvanized steel, this fitting transitions a 16 inch x 8 inch duct inlet to a matching 16 inch x 8 inch outlet using a shortway, vertical, radius throat configuration. The radius throat design reduces turbulence and pressure drop at the elbow. This fitting is built to ACCA and SMACNA standards, making it appropriate for residential and light commercial forced-air distribution systems. Sheet metal workers and HVAC installers use this fitting where a low-profile 90-degree direction change is required within a trunk duct run.

This elbow fits into rectangular trunk duct systems where vertical shortway turns are needed, typically in tight ceiling or floor plenum spaces where a longway elbow will not fit. The shortway geometry allows installation in constrained areas while maintaining the duct cross-section. Compliance with ACCA and SMACNA standards makes it suitable for permitted HVAC installations in residential and light commercial construction.

Key Features

• 90-degree angle for right-angle direction changes in rectangular duct runs
• Shortway vertical configuration for use in space-constrained installations
• Radius throat reduces airflow turbulence and static pressure loss at the elbow
• Hot dip galvanized steel construction resists corrosion in conditioned air applications
• Meets ACCA and SMACNA standards for commercial and residential duct fabrication
• Maintains consistent 16 inch x 8 inch cross-section from inlet to outlet

Compatibility

Designed as an OEM-style sheet metal fitting for rectangular trunk duct systems with a 16 inch x 8 inch duct size, conforming to ACCA and SMACNA ductwork fabrication standards.

Installation Notes

Installation is performed by licensed sheet metal workers or HVAC technicians. The duct system should be de-energized and the air handler shut down before making any modifications to the duct run. Secure all joints with sheet metal screws and seal with UL 181-listed duct mastic or foil tape in accordance with local mechanical codes and SMACNA guidelines. Verify that the shortway orientation matches the as-built duct layout before fastening.
