Southwark Metal 24R_2-1/4X12X5 Duct Boot 2.25x12 to 5 in

Product Description

The SOUTHWARK METAL 24R_2-1/4X12X5 is a 90-degree rectangular-to-round sheet metal duct boot designed to transition from a flat rectangular duct opening to a round collar at a register or grille. The rectangular neck measures 2.25 inches by 12 inches, and the round outlet measures 5 inches in diameter. Fabricated from hot-dip galvanized steel, this fitting delivers corrosion resistance suited to both conditioned spaces and unconditioned areas. HVAC installers use this boot as the final transition fitting between the branch duct and the floor, ceiling, or wall register in forced-air residential and light commercial systems.

This boot fits into standard low-profile floor or wall register applications where a 90-degree turn from the duct run to the register face is required. The 2.25-inch by 12-inch face dimension matches common narrow-slot floor registers used in residential construction. The 5-inch round collar connects directly to 5-inch round branch duct. It is well suited for new construction rough-in and replacement work in residential forced-air heating and cooling systems built to ACCA and SMACNA duct standards.

Key Features

• 90-degree rectangular-to-round transition for register boot installations
• Rectangular neck: 2.25 inches x 12 inches to match standard narrow floor registers
• 5-inch round collar for direct connection to 5-inch branch duct
• Hot-dip galvanized steel construction for corrosion resistance
• Meets ACCA and SMACNA applicable standards for sheet metal ductwork

Compatibility

Designed as an OEM-style sheet metal fitting for residential and light commercial forced-air duct systems requiring a 2.25-inch by 12-inch rectangular register face and a 5-inch round branch duct connection.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal workers in accordance with SMACNA and ACCA duct construction standards. Power down the air handling system and verify the unit is off before cutting into or connecting to existing ductwork. Secure the boot to branch duct using sheet metal screws and seal all joints with UL 181-rated duct mastic or foil tape to prevent air leakage. Do not compress or deform the round collar during installation, as this reduces airflow performance.
