Southwark Metal 21_14X10 Trunk Duct End Cap 14x10

Product Description

The SOUTHWARK METAL 21_14X10 is a sheet metal trunk duct end cap sized at 14 inches by 10 inches, fabricated from hot dip galvanized steel. It is designed to terminate a rectangular trunk duct run, sealing the open end of the duct to prevent conditioned air from escaping and to maintain system static pressure. HVAC installers and sheet metal mechanics fit this cap at the dead-end of trunk duct sections in forced-air distribution systems. The galvanized steel construction resists corrosion in attic, crawlspace, and mechanical room environments where moisture exposure is common.

This end cap is used in residential and light commercial forced-air HVAC systems wherever a 14-inch by 10-inch rectangular trunk duct requires termination. Typical applications include new construction ductwork installations and retrofit or replacement projects where an existing end cap has been damaged or removed. It is installed by sheet metal mechanics or licensed HVAC technicians as part of a complete trunk duct assembly built to ACCA and SMACNA standards.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in exposed or semi-conditioned spaces
• Sized to terminate 14-inch by 10-inch rectangular trunk duct openings
• Trunk-type design for use at dead-end duct terminations
• Manufactured to ACCA and SMACNA applicable standards
• Seals duct end to maintain system static pressure and prevent air loss

Compatibility

Designed as an OEM-style replacement or new-installation end cap for 14-inch by 10-inch rectangular trunk duct systems built to ACCA and SMACNA standards.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Shut down the air handling unit and confirm the system is de-energized before beginning ductwork modifications. Secure the end cap to the trunk duct using sheet metal screws and seal all joints with UL 181-listed duct tape or mastic sealant per local mechanical codes and SMACNA guidelines. Inspect the finished connection for air leakage before returning the system to service.
