Southwark Metal 28RR_4X10X6 Right Hand Register Boot

Product Description

The SOUTHWARK METAL 28RR_4X10X6 is a right-end sheet metal register boot designed for ducted forced-air HVAC systems. Fabricated from hot dip galvanized steel, this fitting transitions from a round duct collar to a rectangular floor or sidewall register opening. The rectangular face measures 4 inches by 10 inches and the round collar measures 6 inches in diameter. It is used to terminate a supply air duct run at a register location and is installed by sheet metal workers, HVAC installers, or mechanical contractors during new construction or duct replacement work.

This register boot is suited for residential and light commercial forced-air heating and cooling systems. The right-hand end configuration means the round collar exits from the right side of the rectangular face when viewed from the front, making it the correct choice for specific duct routing layouts where a left-hand boot would not align with the supply trunk or branch run. Installers working to ACCA and SMACNA duct fabrication standards will find this fitting meets those applicable guidelines.

Key Features

• Right-hand end direction for specific duct routing configurations
• Hot dip galvanized steel construction for corrosion resistance in air distribution applications
• 4 inch by 10 inch rectangular register face matches standard residential register sizes
• 6 inch diameter round collar for connection to standard 6 inch round supply branch duct
• Fabricated to ACCA and SMACNA applicable standards
• Register type fitting for direct termination at floor, sidewall, or ceiling register locations

Compatibility

Designed as an OEM-style sheet metal fitting compatible with standard 6 inch round supply branch ducts terminating at a 4 inch by 10 inch rectangular register opening in residential and light commercial forced-air duct systems.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal mechanic. Shut down the air handling system and de-energize the air handler at the disconnect before beginning duct work. Secure the round collar to the branch duct using sheet metal screws and foil-backed mastic or UL-listed duct tape per SMACNA installation guidelines. Confirm end direction matches the field routing before fastening the boot to the subfloor or framing.
