Southwark Metal 28R_2-1/4X14X6 Duct End Boot 2.25x14 to 6in

Product Description

The SOUTHWARK METAL 28R_2-1/4X14X6 is a rectangular-to-round sheet metal duct end boot designed to transition from a flat rectangular duct opening to a round collar at the register location. Fabricated from hot-dipped galvanized steel, this boot provides corrosion resistance suitable for residential and light commercial forced-air duct systems. The rectangular inlet measures 2.25 inches by 14 inches, and the round outlet is 6 inches in diameter. The center outlet configuration positions the round collar at the midpoint of the rectangular face. HVAC sheet metal installers and ductwork contractors use this fitting during new construction and retrofit installations to terminate supply or return runs at a floor, wall, or ceiling register.

This duct end boot is suited for forced-air heating and cooling systems where a flat rectangular duct must terminate at a round-neck register or grille. The center-discharge design works well in floor applications where a 6-inch round collar aligns to a standard register boot opening. It meets ACCA and SMACNA applicable standards, making it appropriate for residential and light commercial ductwork installations. It is commonly installed by HVAC technicians and sheet metal mechanics as part of supply-air distribution systems connecting trunk lines or branch runs to floor or wall registers.

Key Features

• Hot-dipped galvanized steel construction for corrosion resistance in conditioned-air duct applications
• Rectangular inlet opening: 2.25 inches by 14 inches for compatibility with standard flat-oval and rectangular duct runs
• 6-inch diameter round outlet collar for connection to standard round-neck registers and grilles
• Center outlet configuration for balanced airflow discharge at the register face
• Meets ACCA and SMACNA applicable standards for residential and commercial ductwork

Compatibility

Designed as an OEM-style replacement or new-installation fitting for forced-air duct systems requiring a rectangular-to-round end boot transition with a 2.25-inch by 14-inch rectangular inlet and a 6-inch round outlet.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal mechanic in accordance with SMACNA duct construction standards and local mechanical codes. Shut down the air handler and disconnect power before disturbing any duct section. Secure the boot to the duct with sheet metal screws and seal all joints with UL 181-listed mastic or foil tape to prevent air leakage. Confirm the round collar is fully seated and sealed to the register neck before restoring airflow.
