Southwark Metal 14_8X8 Trunk Duct Elbow 8x8 in 90 Degree

Product Description

The SOUTHWARK METAL 14_8X8 is a 90-degree flat Broadway sheet metal trunk duct elbow fabricated from hot-dip galvanized steel. It transitions an 8-inch x 8-inch duct inlet to an 8-inch x 8-inch outlet, maintaining a consistent cross-section through the turn. The radius throat design reduces turbulence and pressure drop at the bend, supporting efficient airflow in low-velocity trunk systems. This fitting is manufactured to ACCA and SMACNA standards, making it appropriate for residential and light commercial forced-air HVAC ductwork installations. Licensed sheet metal mechanics and HVAC technicians are the primary installers of this type of fitting.

This elbow is suited for rectangular trunk duct systems where a 90-degree directional change is required without a size reduction. Typical applications include main supply or return trunk runs in residential forced-air systems, basement or crawlspace duct layouts, and light commercial air distribution systems where flat Broadway elbows are specified. The radius throat configuration is preferred when minimizing static pressure loss at duct turns is a design priority, consistent with SMACNA duct construction standards and ACCA Manual D airflow requirements.

Key Features

• 90-degree angle suits standard trunk duct directional changes
• Flat Broadway profile fits installations with limited vertical clearance
• Radius throat geometry reduces turbulence and static pressure loss at the bend
• Hot-dip galvanized steel construction resists corrosion in unconditioned spaces
• Consistent 8-inch x 8-inch inlet and outlet sizing eliminates transition fittings
• Manufactured to ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style sheet metal fitting for rectangular trunk duct systems requiring a 90-degree flat Broadway elbow at 8 inches x 8 inches on both the inlet and outlet.

Installation Notes

Installation should be performed by a licensed sheet metal mechanic or HVAC technician in accordance with SMACNA duct construction standards and local mechanical codes. Shut down the air handling system and de-energize the unit before beginning any duct modification or fitting installation. Seal all joints with listed duct sealant or approved foil tape per applicable code requirements. Use appropriate sheet metal tools and wear cut-resistant gloves when handling raw sheet metal edges.
