Southwark Metal 15_30X8 Trunk Duct Angle 30x8 in 45 Degree

Product Description

The SOUTHWARK METAL 15_30X8 is a sheet metal trunk duct angle fitting designed for directional transitions in forced-air HVAC duct systems. Fabricated from hot dip galvanized steel, this fitting delivers a 45-degree shortway turn with a vertical orientation and radius throat geometry. The radius throat reduces turbulence at the elbow, supporting better airflow efficiency through the trunk line. Frame size is 30 inches x 8 inches on both the inlet and outlet. This type of fitting is installed by licensed HVAC technicians and sheet metal workers during duct fabrication or retrofit work on residential and light commercial systems.

This duct angle fitting is suited for rectangular trunk duct systems where a 45-degree shortway turn is required within a confined vertical space. The shortway orientation means the turn radius is taken along the shorter cross-sectional dimension, making it appropriate for installations where ceiling or structural clearances are limited. Both the inlet and outlet dimensions are 30 inches x 8 inches, making this a same-size transition fitting. It meets ACCA and SMACNA standards, which are the recognized industry benchmarks for duct construction and installation practice.

Key Features

• 45-degree shortway trunk duct angle for low-clearance vertical turns
• Radius throat geometry reduces turbulence and improves airflow through the fitting
• Hot dip galvanized steel construction provides corrosion resistance for long service life
• Same-size inlet and outlet: 30 inches x 8 inches both sides, no transition required
• Compliant with ACCA and SMACNA standards for commercial and residential duct fabrication

Compatibility

Designed as an OEM-style sheet metal component for rectangular trunk duct systems requiring a 45-degree shortway vertical elbow at a 30 x 8 inch duct size.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed sheet metal worker in accordance with SMACNA duct construction standards and local mechanical codes. Shut down the air handling system and lock out power before cutting into or connecting to an existing trunk duct. Secure all joints with the appropriate fasteners and seal with UL 181-listed duct sealant or mastic to maintain system air tightness. Verify orientation and airflow direction before final fastening, as shortway fittings are directionally specific.
