Southwark Metal 11102810 Duct End Cap 28x10 Galvanized

Product Description

The SOUTHWARK METAL 11102810 is a rectangular sheet metal end cap designed to terminate and seal the open end of a rectangular trunk duct. Fabricated from hot dip galvanized steel, it provides corrosion resistance suited for long-term use in forced-air HVAC duct systems. Sized at 28 inches by 10 inches, this end cap fits directly over standard rectangular trunk duct of the same dimensions. HVAC sheet metal mechanics and duct installers use it to close off duct runs, prevent air bypass, and maintain system static pressure. Manufactured to ACCA and SMACNA standards, it meets industry requirements for commercial and residential duct fabrication and installation.

This end cap is used in forced-air heating and cooling systems where rectangular trunk duct requires a clean, secure termination. It is appropriate for both new construction duct installations and retrofit or service work where an existing duct run is being extended, capped, or reconfigured. The 28-inch by 10-inch profile fits trunk duct of that cross-section, which is common in residential and light commercial air distribution layouts. Sheet metal installers and HVAC technicians are the primary trade professionals who specify and install this component.

Key Features

• Hot dip galvanized steel construction provides corrosion resistance for long-term duct system use
• Sized at 28 inches by 10 inches to fit standard rectangular trunk duct of the same cross-section
• Rectangular profile designed for trunk duct termination and air bypass prevention
• Manufactured to ACCA and SMACNA applicable standards for duct system components
• Closes off open duct ends to maintain proper system static pressure and airflow balance

Compatibility

Designed as an OEM-style replacement and new-installation end cap for 28-inch by 10-inch rectangular trunk duct systems fabricated and installed to ACCA and SMACNA standards.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Power down the air handling unit and shut off the system before beginning any duct modification or termination work. Secure the end cap to the duct using sheet metal screws and seal all joints with UL 181-listed duct sealant or mastic per SMACNA guidelines to prevent air leakage. Follow applicable local mechanical codes and SMACNA duct construction standards during installation.
