Southwark Metal 16_20X8 Trunk Duct Elbow 20x8 in 90 Degree

Product Description

The SOUTHWARK METAL 16_20X8 is a 90-degree shortway trunk duct elbow fabricated from hot dip galvanized steel. It is designed for use in rectangular sheet metal duct systems where a vertical, shortway turn is required. The elbow features a radius throat profile, which supports smoother airflow transition through the bend compared to a square-throat configuration. Both inlet and outlet dimensions are 20 inches by 8 inches. Licensed HVAC technicians and sheet metal mechanics install this fitting as part of forced-air distribution systems in residential and light commercial applications.

This elbow is used in trunk duct installations where duct routing requires a 90-degree change in direction within a tight horizontal or vertical space. The shortway orientation is suited for situations where the long dimension of the duct runs perpendicular to the turn, reducing the footprint of the fitting. It is a field-fabricated-style component manufactured to ACCA and SMACNA standards, making it appropriate for new construction and retrofit duct work alike.

Key Features

• 90-degree angle for direct right-angle duct transitions
• Shortway, vertical orientation reduces duct footprint at the turn
• Radius throat design promotes smoother airflow through the elbow
• Hot dip galvanized steel construction for corrosion resistance
• Equal inlet and outlet sizing: 20 inches by 8 inches on both ends
• Manufactured to ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style sheet metal fitting for rectangular trunk duct systems sized at 20 inches by 8 inches.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic. Shut down and lock out the air handling system before beginning duct modifications. Secure the elbow to adjacent duct sections using mechanical fasteners and seal all joints with listed duct sealant or UL 181-rated tape per SMACNA installation guidelines. Verify that the shortway orientation and airflow direction are confirmed before final fastening.
