Southwark Metal 16_12X10 Trunk Duct Elbow 12x10 Shortway 90D

Product Description

The SOUTHWARK METAL 16_12X10 is a 90-degree shortway trunk duct elbow fabricated from hot dip galvanized steel. Designed for rectangular sheet metal ductwork, this fitting directs airflow through a tight 90-degree turn using a shortway configuration with a radius throat for improved airflow transitions. Both the inlet and outlet dimensions measure 12 inches by 10 inches, making this a same-size fitting with no reduction. It is installed vertically and is suited for HVAC duct systems where space constraints require a compact elbow. Sheet metal installers and HVAC mechanics work with this type of fitting in forced-air distribution systems.

This elbow is used in rectangular trunk duct assemblies for residential and light commercial forced-air HVAC systems. The shortway orientation is selected when available plenum or ceiling space limits the turning radius in the primary airflow direction. The radius throat design reduces turbulence at the turn compared to a square-throat fitting. Installation typically occurs at trunk-to-trunk transitions or at supply plenum takeoff points where a 90-degree change in duct direction is required. Compliance with ACCA and SMACNA standards makes it appropriate for permitted HVAC installations.

Key Features

• 90-degree shortway elbow with radius throat for reduced turbulence
• Uniform 12 inch by 10 inch inlet and outlet — no size reduction
• Hot dip galvanized steel construction for corrosion resistance
• Vertical orientation for tight-clearance duct routing
• Meets ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style replacement or new-construction fitting for rectangular sheet metal trunk duct systems sized at 12 inches by 10 inches.

Installation Notes

Installation is performed by licensed HVAC mechanics or sheet metal workers. Power down the air handler and close the supply shutoff before modifying any duct section. Secure all joints with sheet metal screws and seal with UL 181-listed mastic or foil tape per SMACNA and local mechanical code requirements. Do not substitute this shortway fitting in applications where duct geometry requires a longway elbow, as the turn radius and pressure drop characteristics differ.
