Southwark Metal 16_12X8 Trunk Duct Elbow 12x8 Shortway 90D

Product Description

The SOUTHWARK METAL 16_12X8 is a 90-degree shortway trunk duct elbow fabricated from hot dip galvanized steel. It is designed for rectangular sheet metal ductwork systems in forced-air HVAC applications. The elbow features a vertical orientation with a radius throat, which reduces turbulence and pressure drop through the turn. Both the inlet and outlet dimensions are 12 inches by 8 inches, making this a same-size transition with no reduction. HVAC sheet metal mechanics and duct fabricators install this fitting during trunk line layout in residential and light commercial air distribution systems.

This elbow is used in rectangular trunk duct systems where a 90-degree direction change is required in a space-constrained installation. The shortway configuration allows the turn to be made in a tighter footprint compared to a longway elbow. The radius throat design helps maintain airflow efficiency through the bend. Typical applications include supply and return trunk lines in forced-air systems installed in attics, basements, crawlspaces, and mechanical rooms. Fabrication and installation follow ACCA and SMACNA standards for sheet metal ductwork.

Key Features

• 90-degree angle for right-angle trunk duct direction changes
• Shortway vertical configuration for installations with limited clearance
• Radius throat design reduces turbulence and improves airflow through the elbow
• Same inlet and outlet size: 12 inches by 8 inches on both ends
• Hot dip galvanized steel construction for corrosion resistance in HVAC environments
• Meets ACCA and SMACNA applicable standards for duct fabrication

Compatibility

Designed as an OEM-style sheet metal fitting for rectangular trunk duct systems in residential and light commercial forced-air HVAC installations requiring a 12 inch by 8 inch 90-degree shortway elbow connection.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic. Power down the air handling system before connecting or modifying ductwork sections. Secure the elbow using sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per SMACNA and local mechanical code requirements. Verify proper support and hanger spacing according to applicable codes before returning the system to service.
