Southwark Metal 14_12X8 Trunk Duct Elbow 12x8 90 Degree

Product Description

The SOUTHWARK METAL 14_12X8 is a 90-degree sheet metal trunk duct elbow designed for rectangular HVAC ductwork systems. Fabricated from hot dip galvanized steel, this elbow features a flat Broadway profile with a radius throat, delivering a smooth directional transition that reduces turbulence and static pressure loss. It measures 12 inches x 8 inches on both the inlet and outlet, making it a straight-size elbow with no reduction. HVAC installers and sheet metal contractors specify this fitting for forced-air systems where a clean 90-degree turn in the main trunk is required. Compliance with ACCA and SMACNA standards ensures it meets industry-accepted duct fabrication requirements.

This elbow is suited for residential and light commercial forced-air HVAC trunk duct installations. The flat Broadway style fits low-clearance applications where traditional radius elbows would not fit within available headroom or framing cavities. The radius throat design reduces airflow separation at the inside of the bend compared to square-throat fittings, supporting better system efficiency. Sheet metal contractors and HVAC mechanics typically install this fitting during new construction or duct replacement work where the main trunk requires a 90-degree change in direction at a 12 x 8 inch duct size.

Key Features

• 90-degree angle provides a precise directional change in rectangular trunk duct runs
• Hot dip galvanized steel construction offers corrosion resistance for long service life
• Flat Broadway profile accommodates low-clearance and tight-space installations
• Radius throat reduces airflow turbulence and static pressure loss at the bend
• Equal inlet and outlet size: 12 inches x 8 inches to 12 inches x 8 inches — no transition required
• Meets ACCA and SMACNA applicable standards for duct fabrication and performance

Compatibility

Designed as an OEM-style sheet metal fitting for rectangular trunk duct systems requiring a 90-degree elbow at 12 inches x 8 inches. Compatible with forced-air duct systems built to ACCA and SMACNA standards.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handling system before connecting or sealing ductwork fittings. Secure connections with sheet metal screws and seal all joints with UL-listed duct sealant or approved mastic to prevent air leakage. Do not use this fitting in applications requiring a reducing elbow — size A and size B are identical at 12 inches x 8 inches.
