Southwark Metal mc-rb59f-4x10x5 Register Boot 4x10x5

Product Description

The SOUTHWARK METAL mc-rb59f-4x10x5 is a 90-degree register boot with flange designed for residential and light commercial HVAC duct distribution systems. Part of the 59F series, this fitting transitions from a round or rectangular duct collar to a floor, wall, or ceiling register opening. It is constructed from steel with a hot-dipped galvanized finish that resists corrosion in typical forced-air installations. The boot measures 4 inches by 10 inches by 5 inches and is intended for installation by HVAC technicians and sheet metal contractors during new construction or retrofit ductwork projects.

This register boot is used where a supply duct run must make a 90-degree turn to terminate at a floor, sidewall, or ceiling register. The flanged collar aids in securing the register grille and provides a clean finished opening. The 4x10x5 inch configuration is a common residential supply-air size and fits standard 4x10 register grilles. It is appropriate for forced-air heating and cooling systems using sheet metal ductwork.

Key Features

• 90-degree configuration routes supply air from duct run to register opening in a single fitting
• Hot-dipped galvanized steel finish provides corrosion resistance in conditioned-air environments
• Integral flange secures register grille and provides a finished appearance at the register face
• 59F series construction for consistent sizing and compatibility with standard sheet metal duct systems
• 4x10x5 inch dimensions fit common residential supply-air register openings

Compatibility

Designed as an OEM-style sheet metal fitting for residential and light commercial forced-air supply duct systems using standard 4x10 register grilles and rectangular duct collars.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with SMACNA duct construction standards and applicable local mechanical codes. Shut down the air handling system before cutting into existing ductwork or securing the boot. Secure the fitting with sheet metal screws and seal all joints with UL 181-rated duct mastic or foil tape to prevent air leakage. Do not rely on duct tape alone for sealing supply-air connections.
