Southwark Metal 1110288 Duct End Cap 28x8 Galvanized

Product Description

The SOUTHWARK METAL 1110288 is a rectangular sheet metal trunk duct end cap designed to terminate the open end of a rectangular trunk duct in forced-air HVAC distribution systems. Fabricated from hot dip galvanized steel, this end cap measures 28 inches in length by 8 inches in width and is built to close off duct runs cleanly and durably. It meets ACCA and SMACNA fabrication standards, making it appropriate for both residential and light commercial duct systems. Licensed HVAC technicians and sheet metal contractors are the typical installers for this type of fitting.

This end cap is intended for use on rectangular trunk duct systems where a duct run must be terminated at a wall, floor cavity boundary, or system endpoint. The 28 x 8 inch profile fits a standard rectangular trunk duct of the same nominal dimensions. It is suited for new construction ductwork as well as replacement and repair work on existing forced-air systems in residential and light commercial applications.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal contractors. Power down the air handling unit and verify the system is off before working inside the duct. The end cap is typically secured using sheet metal screws and sealed with SMACNA-compliant duct sealant or UL 181-rated tape to prevent air leakage. Follow local mechanical codes and SMACNA installation guidelines for duct closure fittings.
