Southwark Metal 16_20X12 Trunk Duct Elbow 90 Degree 20x12

Product Description

The SOUTHWARK METAL 16_20X12 is a 90-degree rectangular trunk duct elbow fabricated from hot dip galvanized steel. It is a shortway, vertical elbow designed for use in sheet metal ductwork systems where a right-angle turn is required in a confined or space-restricted run. The 20 x 12 inch throat dimensions match both the inlet and outlet, making it a direct inline fitting for rectangular trunk duct assemblies. HVAC sheet metal installers and mechanical contractors use this fitting in low-pressure forced-air distribution systems. Construction meets ACCA and SMACNA standards for sheet metal ductwork fabrication.

This elbow is used in residential and light commercial forced-air HVAC duct systems. The shortway geometry keeps the elbow compact along the duct run, making it the preferred choice when ceiling clearance or joist bay depth limits the available turning radius. It fits into rectangular trunk duct configurations where maintaining a consistent 20 x 12 inch cross-section through the turn is required. Typical installations include main trunk transitions, horizontal-to-vertical transitions, and branch takeoff setups in attic, basement, or crawlspace duct runs.

Key Features

• 90-degree shortway rectangular elbow for compact right-angle duct turns
• Hot dip galvanized steel construction for corrosion resistance in HVAC environments
• Consistent 20 x 12 inch cross-section on both inlet and outlet
• Vertical orientation suits standard trunk duct routing configurations
• Fabricated to ACCA and SMACNA standards for low-pressure sheet metal duct systems

Compatibility

Designed as an OEM-style sheet metal fitting for rectangular trunk duct systems with a 20 x 12 inch duct size, conforming to ACCA and SMACNA ductwork fabrication standards.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal mechanics. Power down the air handling unit and close the system before connecting or sealing fittings. Secure all joints with sheet metal screws and seal with mastic sealant or UL 181-listed foil tape per SMACNA guidelines. Follow local mechanical codes for support spacing and hanger requirements on rectangular duct runs.
