Southwark Metal 13_25X10 Trunk Duct Angle 25x10 in 45 Deg

Product Description

The SOUTHWARK METAL 13_25X10 is a 45-degree flat Broadway rectangular trunk duct angle fabricated from hot dip galvanized steel. This fitting redirects airflow in sheet metal trunk duct systems, connecting main trunk runs at a 45-degree offset to accommodate layout changes in tight mechanical spaces. The Broadway (flat) profile keeps the fitting low-profile where ceiling clearance is limited. Sized at 25 inches by 10 inches on both the inlet and outlet faces, it meets ACCA and SMACNA fabrication standards. Licensed HVAC sheet metal mechanics and duct installers are the primary tradespeople who specify and install this fitting.

This trunk duct angle is used in residential and light commercial forced-air HVAC systems where rectangular sheet metal ductwork requires a 45-degree direction change along the trunk run. The flat Broadway configuration is suited for horizontal trunk installations in attics, crawlspaces, and between-floor cavities. Both the A and B dimensions measure 25 inches by 10 inches, making this a straight-through offset fitting with no size transition. It is commonly installed by sheet metal contractors during new construction rough-in or duct replacement work.

Key Features

• 45-degree angle for trunk duct direction changes without full 90-degree turns
• Hot dip galvanized steel construction for corrosion resistance in conditioned and unconditioned spaces
• Flat Broadway rectangular profile for low-profile installations with limited vertical clearance
• Consistent 25 x 10 inch sizing on both sides — no transition, no offset reduction
• Meets ACCA and SMACNA applicable standards for sheet metal duct fabrication

Compatibility

Designed as an OEM-style sheet metal fitting for rectangular trunk duct systems requiring a 45-degree flat Broadway angle at the 25 x 10 inch duct size.

Installation Notes

Installation is performed by licensed sheet metal mechanics or HVAC technicians following SMACNA duct construction standards. The system blower must be powered down and the disconnect locked out before connecting or modifying any duct section. Secure all joints with sheet metal screws and seal with approved duct mastic or UL 181-rated tape per local mechanical code requirements. Do not substitute standard drive-and-cleat connections rated for lesser pressure classes than the designed system static pressure.
