The SOUTHWARK METAL 1110228-24G is a sheet metal end cap designed to close off the open end of rectangular HVAC ductwork. End caps are essential duct fittings used to terminate supply or return air runs, preventing uncontrolled airflow loss at duct termination points. This fitting measures 22 x 8 inches and is fabricated from 24-gauge sheet metal. HVAC installers and sheet metal mechanics use end caps during duct system installation and service to maintain system pressure balance and protect duct interiors from debris and drafts.
This end cap is suited for residential and light commercial HVAC duct systems where rectangular duct runs require a clean, sealed termination. Typical applications include capping unused duct takeoffs, sealing the end of a supply trunk line during phased construction, or closing off a branch run that has been rerouted. The 22 x 8 inch size corresponds to a standard rectangular duct dimension commonly found in forced-air heating and cooling systems.
Designed as an OEM-style sheet metal replacement fitting for standard 22 x 8 inch rectangular HVAC duct systems used in residential and light commercial forced-air applications.
Installation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Power down the air handling unit and verify the system is de-pressurized before fitting or removing duct termination components. Secure the end cap with sheet metal screws and seal all joints with UL 181-rated duct sealant or foil tape per local mechanical code requirements. Follow applicable SMACNA standards for duct construction and sealing.
