Southwark Metal 16_25X10 Trunk Duct Elbow 25x10 90 Degree

Product Description

The SOUTHWARK METAL 16_25X10 is a rectangular sheet metal trunk duct elbow designed for 90-degree directional changes in forced-air HVAC duct systems. Fabricated from hot dip galvanized steel, this fitting delivers durable corrosion resistance suited to long-term installation in supply trunk lines. The shortway, vertical configuration is engineered to make tight turns in constrained plenum or trunk runs where space is limited. With a face size of 25 inches by 10 inches on both the inlet and outlet, it fits directly into standard rectangular trunk duct systems without transition. Licensed HVAC sheet metal installers and ductwork contractors are the primary installers of this fitting.

This elbow is used in residential and light commercial forced-air HVAC systems where rectangular trunk duct changes direction at a 90-degree angle. The shortway orientation minimizes the depth footprint of the turn, making it well-suited for installations in tight mechanical rooms, low-clearance attics, crawlspaces, and basement ceilings. It connects to standard 25-inch by 10-inch rectangular duct sections and is appropriate for supply or return trunk runs requiring a vertical elbow transition.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in HVAC duct environments
• 90-degree angle for direct perpendicular trunk duct transitions
• Shortway profile reduces installation depth compared to longway elbows
• Vertical, rectangular configuration matches standard trunk duct geometry
• Consistent 25 x 10 inch face dimensions on both inlet and outlet
• Fabricated to ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style sheet metal fitting for use with standard rectangular trunk duct systems sized at 25 inches by 10 inches in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with SMACNA duct construction standards and applicable local mechanical codes. Shut down and de-energize the air handling system before beginning any ductwork modification or fitting installation. Secure the elbow to adjoining duct sections using sheet metal screws and seal all joints with UL-listed foil tape or duct mastic to maintain system pressure and efficiency. Do not modify the fitting geometry or attempt field fabrication of connection flanges.
