Southwark Metal 1141R1210 Trunk Duct Angle 45 Degree

Product Description

The SOUTHWARK METAL 1141R1210 is a 45-degree shortway trunk duct angle fabricated from hot dip galvanized steel. This fitting directs rectangular sheet metal ductwork through a 45-degree turn on the short dimension of the duct cross-section, making it the right choice when vertical layout space is limited. Sized at 12 inches by 10 inches on both the inlet and outlet, it is used in low-pressure forced-air distribution systems. Sheet metal mechanics and HVAC installers use this fitting when building or extending trunk duct runs in residential and light commercial applications.

This trunk duct angle is suited for rectangular supply or return trunk duct systems where a 45-degree directional change is required along the shortway axis. The vertical orientation means the turn occurs in the vertical plane. Typical install scenarios include basement, crawlspace, and attic duct runs where the duct path must change direction to route around structural framing or mechanical equipment. Both the inlet and outlet dimensions are 12 inches by 10 inches, so no reducing transitions are needed at either end when the trunk is a consistent size throughout.

Key Features

• 45-degree shortway angle for space-efficient directional changes in the short cross-section dimension
• Hot dip galvanized steel construction for corrosion resistance in typical HVAC duct environments
• Consistent 12 inch by 10 inch inlet and outlet dimensions — no reducing fittings required at connection points
• Vertical, rectangular configuration suits a wide range of trunk duct routing layouts
• Meets ACCA and SMACNA applicable standards for sheet metal ductwork fabrication and performance

Compatibility

Designed as an OEM-style sheet metal fitting for rectangular trunk duct systems sized at 12 inches by 10 inches, following ACCA and SMACNA standards for low-pressure forced-air distribution.

Installation Notes

Installation should be performed by a licensed sheet metal mechanic or qualified HVAC technician. Shut down the air handling unit and confirm the system is de-energized before cutting into or extending an existing duct run. Secure the fitting with sheet metal screws and seal all longitudinal seams and transverse joints with UL 181-rated mastic or approved foil tape per SMACNA guidelines. Support the fitting and adjacent ductwork with hangers at intervals consistent with SMACNA hanger and support requirements.
